90869-13-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90869-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,6 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90869-13:
(7*9)+(6*0)+(5*8)+(4*6)+(3*9)+(2*1)+(1*3)=159
159 % 10 = 9
So 90869-13-9 is a valid CAS Registry Number.

A 5 + 1 Protic Acid Assisted Aza-Pummerer Approach for Synthesis of 4-Chloropiperidines from Homoallylic Amines

Ebule, Rene,Mudshinge, Sagar,Nantz, Michael H.,Mashuta, Mark S.,Hammond, Gerald B.,Xu, Bo

, p. 3249 - 3259 (2019)

We report that HCl·DMPU induces the formation of (thiomethyl)methyl carbenium ion from DMSO under mild conditions. Homoallylic amines react with this electrophile to generate 4-chloropiperidines in good yields. The method applies to both aromatic and aliphatic amines. The use of HCl·DMPU as both non-nucleophilic base and chloride source constitutes an environmentally benign alternative for piperidine formation. The reaction has a broad substrate scope, and the conditions offer good chemical yields with high functional group tolerance and scalability.
