36193-36-9 Usage

Description

This alkaloid is also a constituent of the leaves of Rhazya stricta and is isolated by chromatography on an alumina column followed by recrystallization from cyclohexane when it forms colourless plates. The ultraviolet spectrum shows an absorption maximum at 213 mJi and inflexions at 220 and 275 mμ

Check Digit Verification of cas no

The CAS Registry Mumber 36193-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,1,9 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 36193-36:
(7*3)+(6*6)+(5*1)+(4*9)+(3*3)+(2*3)+(1*6)=119
119 % 10 = 9
So 36193-36-9 is a valid CAS Registry Number.

Catalytically Asymmetric Pd/Norbornene Catalysis: Enantioselective Synthesis of (+)-Rhazinal, (+)-Rhazinilam, and (+)-Kopsiyunnanine C1-3

Zhao, Kun,Xu, Shibo,Pan, Chongqing,Sui, Xianwei,Gu, Zhenhua

supporting information, p. 3782 - 3785 (2016/08/16)

A catalytically asymmetric palladium/norbornene-catalyzed reaction is reported, where α-aryl tetrahydroquinoline derived phosphoramidite L15 is found to be the optimum ligand. Taking advantage of this transformation, the concise and unified enantioselective syntheses of (+)-rhazinal, (+)-rhazinilam, and (+)-kopsiyunnanine C1, C2, and C3 are realized.

Solvent-controlled switchable C-H alkenylation of 4-aryl-1H-pyrrole-3-carboxylates: Application to the total synthesis of (±)-rhazinilam

Su, Youla,Zhou, Haipin,Chen, Jiaxuan,Xu, Jinyi,Wu, Xiaoming,Lin, Aijun,Yao, Hequan

, p. 4884 - 4887 (2015/04/27)

A solvent-controlled switchable C-H alkenylation of 4-aryl-1H-pyrrole-3-carboxylates via a Pd(OAc)2 catalyzed oxidative Heck reaction was first realized. The corresponding C2 and C5 alkenylation products were obtained in good yields with high regioselectivities, respectively. The selective C5-alkenylation was successfully applied to the total synthesis of (±)-rhazinilam.

Chemical synthesis of aspidosperma alkaloids inspired by the reverse of the biosynthesis of the rhazinilam family of natural products

McMurray, Lindsay,Beck, Elizabeth M.,Gaunt, Matthew J.

, p. 9288 - 9291 (2012/10/30)

Pyrrole reduction: Iterative metal-catalyzed C-H functionalization reactions facilitated the preparation of a highly substituted pyrrole derivative. This derivative could be transformed into the pyrrole-containing secondary metabolite, rhazinilam, which could in turn be transformed through a reductive transannular cascade process into the structurally complex pyrrolidine-containing alkaloid natural product, aspidospermidine.
