3651-14-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3651-14-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,5 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3651-14:
(6*3)+(5*6)+(4*5)+(3*1)+(2*1)+(1*4)=77
77 % 10 = 7
So 3651-14-7 is a valid CAS Registry Number.

Tandem Synthesis of Tetrasubstituted NH Pyrroles from Simple Nitriles

Kim, Hyeongsu,Xuan, Zi,Hyun Kim, Ju

supporting information, p. 3336 - 3340 (2021/09/09)

An efficient tandem route to obtain tetrasubstituted NH pyrroles in a one-pot manner has been developed, staring from simple nitriles, ethyl bromoacetates, and zinc. This reaction involves oxidative dimerization of the zinc bromide complex of β-enaminoesters using cerium ammonium nitrate (CAN) as an oxidant, affording 2,3,4,5-tetrasubstituted pyrroles in yields up to 91%.

Divergent Synthesis of Multisubstituted Unsymmetric Pyrroles and Pyrrolin-4-ones from Enamino Esters via Copper-Catalyzed Aerobic Dimerization

Chen, Zhi-Wei,Zheng, Lei,Liu, Jin

, p. 3051 - 3060 (2019/05/24)

A facile synthetic method to access multisubstituted unsymmetric pyrrole and pyrrolin-4-one derivatives is disclosed. In the presence of Cu(OAc)2 and KOAc, substituted pyrrole derivatives are produced in good yields (up to 93 %) through oxidative cyclization of enamino esters. Meanwhile, using CuCl2 and TFA (trifluoroacetic acid), pyrrolin-4-one derivatives are obtained in excellent yields (up to 94 %) through 1,2-aryl migration. A wide range of functional groups have been tolerated, and a reliable method for the synthesis of valuable multisubstituted pyrroles and pyrrolin-4-ones has been developed.
