56893-10-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 56893-10-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,9 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56893-10:
(7*5)+(6*6)+(5*8)+(4*9)+(3*3)+(2*1)+(1*0)=158
158 % 10 = 8
So 56893-10-8 is a valid CAS Registry Number.

Silica gel-promoted synthesis of multisubstituted spiroindolenines from tryptamines and γ-chloro-α,β-unsaturated ketones

Liu, Qiang-Qiang,Zheng, Chao,You, Shu-Li

, (2020/12/02)

Here we report a one-pot synthesis of multisubstituted spiroindolenines from a series of tryptamine derivatives with γ-chloro-α,β-unsaturated ketones. The reaction sequence consists of base-induced condensation and silica gel-promoted intramolecular Michael addition. The target molecules are afforded in up to 90% yield with up to >20:1 diastereoselectivity.

Rh-Catalyzed diastereoselective desymmetrization of enone tethered-cyclohexadienones: Via tandem arylative cyclization

Jadhav, Sandip B.,Thopate, Satish B.,Nanubolu, Jagadeesh Babu,Chegondi, Rambabu

supporting information, p. 1937 - 1946 (2019/02/20)

The rhodium-catalyzed arylative cyclization of enone tethered-cyclohexadienones has been developed with high efficiency, thus providing cis-fused bicyclic enones in good yields and with excellent diastereoselectivities. Furthermore, this mild transformation has a broad range of substrate scope and excellent functional group tolerance. In addition, bicyclic products have an enone functionality, which can be a synthetically valuable handle for further transformations.

Asymmetric 1,4-Conjugate Addition of Diarylphosphines to α,β,γ,δ-Unsaturated Ketones Catalyzed by Transition-Metal Pincer Complexes

Yang, Xiang-Yuan,Tay, Wee Shan,Li, Yongxin,Pullarkat, Sumod A.,Leung, Pak-Hing

supporting information, p. 5196 - 5201 (2015/11/09)

An enantioselective asymmetric 1,4-addition of diarylphosphines to linear α,β,γ,δ-unsaturated dienones was developed. A series of chiral PCP- and PCN-transition-metal (Pd, Pt and Ni) pincers, themselves prepared catalytically via asymmetric hydrophosphination, were sequentially screened to reveal the roles of backbone architecture and metal ion in catalyst design. The selected ester-functionalized PCP-palladium pincer afforded the chiral 1,4-phosphine adducts in excellent yields with up to >99% ee. The same catalyst when utilized for the hydrophosphination of an α,β,γ,δ-unsaturated malonate ester also revealed the critical role played by the ester functionality on the ligand backbone in dictating the enantioselectivity of the 1,6-adduct.

Chemically Induced Anion Radical Cycloadditions: Intramolecular Cyclobutanation of Bis(enones) via Homogeneous Electron Transfer

Yang, Jingkui,Felton, Greg A. N.,Bauld, Nathan L.,Krische, Michael J.

, p. 1634 - 1635 (2007/10/03)

The first examples of anion radical cycloaddition induced by homogeneous electron transfer from chemical agents are described. Specifically, upon exposure to chrysene anion radical, bis(enone) substrates are found to engage in stereoselective intramolecular [2 + 2] cycloaddition. These studies, along with the corresponding electrochemically initiated reactions, provide insight into this fundamentally new pattern of reactivity and support the feasibility of expanding this novel reaction type.
