188302-42-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188302-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,3,0 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 188302-42:
(8*1)+(7*8)+(6*8)+(5*3)+(4*0)+(3*2)+(2*4)+(1*2)=143
143 % 10 = 3
So 188302-42-3 is a valid CAS Registry Number.

Iridium-Catalyzed Reductive Alkylations of Secondary Amides

Ou, Wei,Han, Feng,Hu, Xiu-Ning,Chen, Hang,Huang, Pei-Qiang

supporting information, p. 11354 - 11358 (2018/08/28)

Reported herein is the first direct, metal-catalyzed reductive functionalization of secondary amides to give functionalized amines and heterocycles. The method is shown to have exceptionally broad scope with respect to suitable nucleophiles, which cover both hard and soft C nucleophiles as well as a P nucleophile. The reaction exhibits good chemoselectivity and tolerates several sensitive functional groups.

A general catalytic allylation using allyltrimethoxysilane

Yamasaki, Shingo,Fujii, Kunihiko,Wada, Reiko,Kanai, Motomu,Shibasaki, Masakatsu

, p. 6536 - 6537 (2007/10/03)

A general and mild catalytic allylation of carbonyl compounds, applicable to aldehydes, ketones, and imines is developed using allyltrimethoxysilane as the allylating reagent. The reaction proceeds smoothly with 1-10 mol % of CuCl and TBAT in THF at ambie

Synthesis of azetidines by electrophilic selenium-induced cyclization of homoallylic benzylamines

Berthe, Benedicte,Outurquin, Francis,Paulmierz.ast, Claude

, p. 1393 - 1396 (2007/10/03)

Homoallyl benzylamines prepared by allylation of the corresponding N-benzylimines, have been subjected to a selenium-induced cyclization under various conditions. At room temperature. the 4-exo and the 5-endo modes are competitive. In acetonitrile, the azetidine has been isolated as the major cyclization product, especially for homoallylamines derived from ketimines. With an excess or selenium reagent, 3-halopyrrolidines have been obtained.
