20371-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20371-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,7 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20371-41:
(7*2)+(6*0)+(5*3)+(4*7)+(3*1)+(2*4)+(1*1)=69
69 % 10 = 9
So 20371-41-9 is a valid CAS Registry Number.

Efficient and selective solid-phase synthesis of trans 3-alkyl β-lactams from nonactivated acid chlorides

Delpiccolo, Carina M. L.,Mata, Ernesto G.

, p. 4085 - 4088 (2004)

An efficient and stereoselective procedure for a rapid access to diverse trans 3-alkyl β-lactams by solid-phase methodology is described.

Palladium-Catalyzed Migratory Insertion of Carbenes and C-C Cleavage of Cycloalkanecarboxamides

Zhang, Peng,Zeng, Jia,Pan, Ping,Zhang, Xue-Jing,Yan, Ming

supporting information, p. 536 - 541 (2022/01/20)

A palladium catalyzed reaction of cycloalkanecarboxamides and diazomalonates or bis(phenylsulfonyl)diazomethane has been developed. The reaction proceeds via carbene migratory insertion and cascade C-C cleavage pathways. Cycloalkanecarboxamides with four to seven membered rings are applicable in the transformation. A series of ring opening products were prepared with moderate yields. The finding provides valuable clues for the development of new reactions involving carbene migratory insertion and the cleavage of unstrained C(sp3)-C(sp3) bonds.

2-Imidazole as a Substitute for the Electrophilic Group Gives Highly Potent Prolyl Oligopeptidase Inhibitors

Arja, Khaled,Auno, Samuli,Dillemuth, Pyry M. J.,Kilpel?inen, Tommi P.,Lahtela-Kakkonen, Maija K.,My?h?nen, Timo T.,P?tsi, Henri T.,Wallén, Erik A. A.

Different five-membered nitrogen-containing heteroaromatics in the position of the typical electrophilic group in prolyl oligopeptidase (PREP) inhibitors were investigated and compared to tetrazole. The 2-imidazoles were highly potent inhibitors of the pr

Auxiliary-controlled diastereoselective synthesis of a syn C-6-epimer of the ADAM 10 inhibitor GI254023X

Nair, Shankari,Zeevaart, Jan Rijn,Hunter, Roger

, p. 90 - 102 (2020/10/08)

ADAM10 is a cell surface-expressed metalloprotease involved in various cell adhesion and proteolytic processes, in which biological studies have linked an over-expression of ADAM10 to the development and progression of various types of diseases including cancer. GI254023X is a hydroxamate metalloprotease inhibitor known for ADAM10 activity inhibition, but for which structure-activity based biological information for assessing anti-tumour and anti-inflammatory activity is lacking. In this work, an Evans’ asymmetric boron aldol reaction was used to synthesise a syn C-6-epimer of GI254023X intended for biological evaluation against the natural inhibitor.

Enantioselective Remote C(sp3)-H Cyanation via Dual Photoredox and Copper Catalysis

Chen, Hui,Jin, Weiwei,Yu, Shouyun

supporting information, p. 5910 - 5914 (2020/08/12)

The remote C(sp3)-H cyanation of carboxamides has been described by merging photoredox and copper catalysis in a site-selective and enantiocontrolled manner. The protocol is the integration of photoinduced and nitrogen-centered radical-mediated intermolecular hydrogen atom transfer with chiral copper-complex-catalyzed radical cyanation. This strategy gives enantio-enriched cyanated amides in high yields.

Identification of diphenylalkylisoxazol-5-amine scaffold as novel activator of cardiac myosin

Boggu, Pulla Reddy,Venkateswararao, Eeda,Manickam, Manoj,Sharma, Niti,Kang, Jong Seong,Jung, Sang-Hun

, (2020/09/16)

To identify novel potent cardiac myosin activator, a series of diphenylalkylisoxazol-5-amine compounds 4–7 have been synthesized and evaluated for cardiac myosin ATPase activation. Among the 37 compounds, 4a (CMA at 10 μM = 81.6%), 4w (CMA at 10 μM = 71.2%) and 6b (CMA at 10 μM = 67.4%) showed potent cardiac myosin activation at a single concentration of 10 μM. These results suggested that the introduction of the amino-isoxazole ring as a bioisostere for urea group is acceptable for the cardiac myosin activation. Additional structure–activity relationship (SAR) studies were conducted. Para substitution (-Cl, –OCH3, -SO2N(CH3)2) to the phenyl rings or replacement of a phenyl ring with a heterocycle (pyridine, piperidine and tetrahydropyran) appeared to attenuate cardiac myosin activation at 10 μM. Additional hydrogen bonding acceptor next to the amino group of the isoxazoles did not enhance the activity. The potent isoxazole compounds showed selectivity for cardiac myosin activation over skeletal and smooth muscle myosin, and therefore these potent and selective isoxazole compounds could be considered as a new series of cardiac myosin ATPase activators for the treatment of systolic heart failure.

Selective Inhibitors of a Human Prolyl Hydroxylase (OGFOD1) Involved in Ribosomal Decoding

Thinnes, Cyrille C.,Lohans, Christopher T.,Abboud, Martine I.,Yeh, Tzu-Lan,Tumber, Anthony,Nowak, Rados?aw P.,Attwood, Martin,Cockman, Matthew E.,Oppermann, Udo,Loenarz, Christoph,Schofield, Christopher J.

supporting information, p. 2019 - 2024 (2019/01/11)

Human prolyl hydroxylases are involved in the modification of transcription factors, procollagen, and ribosomal proteins, and are current medicinal chemistry targets. To date, there are few reports on inhibitors selective for the different types of prolyl hydroxylases. We report a structurally informed template-based strategy for the development of inhibitors selective for the human ribosomal prolyl hydroxylase OGFOD1. These inhibitors did not target the other human oxygenases tested, including the structurally similar hypoxia-inducible transcription factor prolyl hydroxylase, PHD2.

N-Acyl pyrazoles: Effective and tunable inhibitors of serine hydrolases

Otrubova, Katerina,Chatterjee, Shreyosree,Ghimire, Srijana,Cravatt, Benjamin F.,Boger, Dale L.

, p. 1693 - 1703 (2019/03/21)

A series of N-acyl pyrazoles was examined as candidate serine hydrolase inhibitors in which the active site acylating reactivity and the leaving group ability of the pyrazole could be tuned not only through the nature of the acyl group (reactivity: amide

Synthesis of Ynolates via Double Deprotonation of Nonbrominated Esters

Sun, Jun,Yoshiiwa, Toshiya,Iwata, Takayuki,Shindo, Mitsuru

supporting information, p. 6585 - 6588 (2019/09/30)

Herein, we report a double deprotonation method used for the preparation of ynolates starting from nonbrominated 2,6-di-tert-butylphenyl esters. The current method is superior to the previously described double lithium/halogen exchange approach because easily accessible starting materials are used. This method will be especially useful for preparation of ynolates bearing functional groups in organic synthesis.

Strategic Approach to the Metamorphosis of γ-Lactones to NH γ-Lactams via Reductive Cleavage and C-H Amidation

Jung, Hoi-Yun,Chang, Sukbok,Hong, Sungwoo

supporting information, p. 7099 - 7103 (2019/09/07)

A new approach has elaborated on the conversion of γ-lactones to the corresponding NH γ-lactams that can serve as γ-lactone bioisosteres. This approach consists of reductive C-O cleavage and an Ir-catalyzed C-H amidation, offering a powerful synthetic tool for accessing a wide range of valuable NH γ-lactam building blocks starting from γ-lactones. The synthetic utility was further demonstrated by the late-stage transformation of complex bioactive molecules and the asymmetric transformation.
