Check Digit Verification of cas no

The CAS Registry Mumber 102632-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,6,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102632-99:
(8*1)+(7*0)+(6*2)+(5*6)+(4*3)+(3*2)+(2*9)+(1*9)=95
95 % 10 = 5
So 102632-99-5 is a valid CAS Registry Number.

Allylsamarium bromide-mediated cascade cyclization of homoallylic esters. Synthesis of 2-(2-hydroxyalkyl)cyclopropanols and 2-(2-hydroxyethyl)bicyclo[2.1.1]hexan-1-ols

Shen, Mengmeng,Tu, Yawei,Xie, Guanqun,Niu, Qingsheng,Mao, Hui,Xie, Tingting,Flowers, Robert A.,Lv, Xin,Wang, Xiaoxia

, p. 52 - 61 (2015)

In continuation of our previous study on the intramolecular reductive coupling of simple homoallylic esters promoted by allylSmBr/HMPA/H2O, which afforded a facile synthesis of 2-(2-hydroxyalkyl)cyclopropanols, here we report the reductive casc

Synthesis of a trans-chelating chiral diphosphine ligand with only planar chirality and its application to asymmetric hydrosilylation of ketones

Kuwano,Uemura,Saitoh,Ito

, p. 1327 - 1330 (1999)

Optically active diphosphine (S,S)-2,2-bis[(diethylphosphino)methyl]- 1,1-biferrocene (abbreviated to (S,S)-EtTRAP-H) was synthesized from ferrocenyloxazoline derived from-L-valinol in 47% overall yield. The new chiral ligand, (S,S)-EtTRAP-H, which coordinates to a rhodium atom in a trans-chelating manner, was effective for asymmetric hydrosilylation of ketones to give optically active secondary alcohols with up to 94% ee.

Easy selective generation of (lithiomethyl)cyclopropane or homoallyllithium by a chlorine-lithium exchange

Pastor, Isidro M.,Pe?afiel, Itziar,Yus, Miguel

, p. 6870 - 6872 (2008)

The reaction of (chloromethyl)cyclopropane 5 with lithium and a catalytic amount of DTBB (5 mol %) in the presence of different carbonyl compounds [Et2CO, n-Pr2CO, (c-C3H5)2CO, (CH2)5CO, PhCOMe, t-BuCHO, i-PrCHO, PhCHO] as electrophiles in THF at -78 °C leads, after hydrolysis with water, to the corresponding cyclopropyl alcohols 6. However, when the same starting material is lithiated using naphthalene as the arene catalyst in ether at 0 °C and then reacts with the same series of electrophiles, the final hydrolysis with water yields the corresponding unsaturated alcohols 7.

Allylation of epoxides with allylic indium reagents

Hirashita, Tsunehisa,Mitsui, Kazuma,Hayashi, Yousuke,Araki, Shuki

, p. 9189 - 9191 (2004)

Allylindium sesquihalide reacts with epoxide to give homoallyl alcohol via a 1,2-shift reaction. In contrast, allylindate gives the ring-opening product without rearrangement.

Yb(OTf)3 catalyzed highly regioselective allylation of aromatic epoxides: An efficient route to bishomoallyl alcohols

Likhar, Pravin R.,Kumar, Manyam Praveen,Bandyopadhyay, Ananda K.

, p. 3333 - 3335 (2002)

Anhydrous ytterbium(III) triflate-catalyzed ring opening of aromatic 1,2-epoxides with allyltributyltin in THF results in the formation of bishomoallyl alcohols in excellent yields and with complete regioselectivity. The results are compared with those ob

Highly Enantioselective Construction of Dihydrooxazines via Pd-Catalyzed Asymmetric Carboetherification

Li, Na,Sun, Baozhen,Liu, Shuang,Zhao, Jinbo,Zhang, Qian

supporting information, p. 190 - 193 (2020/01/02)

A straightforward synthesis of highly enantioenriched 5,6-dihydro-4H-1,2-oxazines is realized by Pd-catalyzed asymmetric carboetherification of γ,δ-alkenyl oximes with (hetero)aryl and alkenyl halides in the presence of a commercially available bisphosphine ligand. The enantioenriched products can be facilely converted to functionalized alcohols with high fidelity of chiral transfer.

Copper-Catalyzed Cope-Type Hydroamination of Nonactivated Olefins toward Cyclic Nitrones: Scope, Mechanism, and Enantioselective Process Development

Zhang, Mengru,Liu, Shuang,Li, Hexin,Guo, Yajing,Li, Na,Guan, Meihui,Mehfooz, Haroon,Zhao, Jinbo,Zhang, Qian

supporting information, p. 12620 - 12627 (2019/09/16)

The catalytic synthesis of cyclic nitrones, an important type of functional molecules for both synthetic chemistry and related fields, remains underdeveloped. Herein we report the copper-catalyzed Cope-type hydroamination of oximes with pendant nonactivated olefins, which enables facile access to a series of five- and six-membered cyclic nitrones under mild conditions. In this study, heterocycle-tethered oximes were employed in the Cope-type hydroamination reaction for the first time. High enantioselectivity was achieved for carbon-tethered γ,δ-vinyl oximes to afford enantioenriched five-membered cyclic nitrones. The results of preliminary mechanistic studies indicate a mononuclear catalytic species and a unified catalytic pathway over a large temperature range.
