105643-16-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 105643-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,6,4 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 105643-16:
(8*1)+(7*0)+(6*5)+(5*6)+(4*4)+(3*3)+(2*1)+(1*6)=101
101 % 10 = 1
So 105643-16-1 is a valid CAS Registry Number.

Regiocontrol and Stereoselectivity in Tungsten-Bipyridine Catalysed Allylic Alkylation

Lehmann, Juerg,Lloyd-Jones, Guy C.

, p. 8863 - 8874 (1995)

Tungsten-bipyridine complexes, generated in situ, catalyse the allylic alkylation of isocinnamyl methyl carbonate by dimethyl sodiomalonate with complete syn-stereoselectivity.When para substituted aryl-allyl methyl carbonates are employed, the regioselectivity correlates with Swain-Lupton parameters.Cross-over experiments demonstrate that the reactions do not proceed via the conventional 0> -> II allyl>+ -> 0 allyl-Nu> catalytic cycle.

A Re2O7catalyzed cycloetherification of monoallylic diols

Wan, Xiaolong,Hu, Jiadong,Xu, Dongyang,Shang, Yang,Zhen, Yanxia,Hu, Chenchen,Xiao, Fan,He, Yu-Peng,Lai, Yisheng,Xie, Weiqing

supporting information, p. 1090 - 1093 (2017/03/02)

A Re2O7catalyzed cycloetherification of monoallylic diols is described. The reaction features short reaction time, mild reaction conditions and exclusive E selectivity. A wide range of monoallylic alcohols with alkyl or aryl substituents on olefin smoothly undergo ring closure to deliver corresponding oxa-heterocycles. The reaction is also operationally simple and not sensitive to air and moisture.

Highly efficient kinetic resolution of allylic alcohols with terminal double bond

Marques, Francisco A.,Oliveira, Marcos A.,Frensch, Gustavo,Sales Maia, Beatriz Helena L. N.,Barison, Andersson,Lenz, Cesar A.,Guerrero Jr., Palimecio G.

body text, p. 696 - 700 (2012/06/04)

In this study, the lipase-catalyzed kinetic resolution (Novozyme 435) was employed to prepare chiral allylic alcohols and acetates with terminal double bonds in enantiomeric excesses ranging from 94 to >99 %.
