30160-48-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30160-48-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,1,6 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 30160-48:
(7*3)+(6*0)+(5*1)+(4*6)+(3*0)+(2*4)+(1*8)=66
66 % 10 = 6
So 30160-48-6 is a valid CAS Registry Number.

Preparation of Heterocycles via Visible-Light-Driven Aerobic Selenation of Olefins with Diselenides

Zhang, Qing-Bao,Yuan, Pan-Feng,Kai, Liang-Lin,Liu, Kai,Ban, Yong-Liang,Wang, Xue-Yang,Wu, Li-Zhu,Liu, Qiang

supporting information, p. 885 - 889 (2019/02/14)

The aerobic dehydrogenative cyclization of alkenes with easily accessible diselenides facilitated by visible light is reported. Notably, the features of this transition-metal-free protocol are pronounced efficiency and practicality, good functional group

Sterically Demanding Oxidative Amidation of α-Substituted Malononitriles with Amines Using O2

Li, Jing,Lear, Martin J.,Hayashi, Yujiro

supporting information, p. 9060 - 9064 (2016/07/26)

An efficient amidation method between readily available 1,1-dicyanoalkanes and either chiral or nonchiral amines was realized simply with molecular oxygen and a carbonate base. This oxidative protocol can be applied to both sterically and electronically challenging substrates in a highly chemoselective, practical, and rapid manner. The use of cyclopropyl and thioether substrates support the radical formation of α-peroxy malononitrile species, which can cyclize to dioxiranes that can monooxygenate malononitrile α-carbanions to afford activated acyl cyanides capable of reacting with amine nucleophiles.

Umpolung Amide Synthesis using substoichiometric N-iodosuccinimide (NIS) and oxygen AS a terminal oxidant

Schwieter, Kenneth E.,Shen, Bo,Shackleford, Jessica P.,Leighty, Matthew W.,Johnston, Jeffrey N.

supporting information, p. 4714 - 4717 (2015/04/27)

Umpolung Amide Synthesis (UmAS) provides direct access to amides from an α-bromo nitroalkane and an amine. Based on its mechanistic bifurcation after convergent C-N bond formation, depending on the absence or presence of oxygen, UmAS using substoichiometric N-iodosuccinimide (NIS) under aerobic conditions has been developed. In combination with the enantioselective preparation of α-bromo nitroalkane donors, this protocol realizes the goal of enantioselective α-amino amide and peptide synthesis based solely on catalytic methods.
