135663-93-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135663-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,6 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135663-93:
(8*1)+(7*3)+(6*5)+(5*6)+(4*6)+(3*3)+(2*9)+(1*3)=143
143 % 10 = 3
So 135663-93-3 is a valid CAS Registry Number.

Cobalt-Catalyzed C8-Dienylation of Quinoline-N-Oxides

Khan, Salman,Nair, Akshay M.,Shukla, Rahul K.,Volla, Chandra M. R.

supporting information, p. 17042 - 17048 (2020/08/05)

An efficient Cp*CoIII-catalyzed C8-dienylation of quinoline-N-oxides was achieved by employing allenes bearing leaving groups at the α-position as the dienylating agents. The reaction proceeds by CoIII-catalyzed C?H activation of qui

Highly stereoselective kinetic resolution of α-allenic alcohols: An enzymatic approach

Li, Wenhua,Lin, Zuming,Chen, Long,Tian, Xuechao,Wang, Yan,Huang, Sha-Hua,Hong, Ran

supporting information, p. 603 - 606 (2016/01/20)

A highly efficient lipase AK-catalyzed direct kinetic resolution of a variety of α-allenic alcohols was developed. With the complementary to previous studies, the current reaction system is effective on a broad range of substituents (R1) at C(1), such as alkyl, aryl, alkenyl, and alkynyl groups. The Jones-Burgess empirical model was modified to interpret the reversed selectivity during the acetylation of secondary alcohol. The methyl group at C(2) of allenic alcohols implied a small structural adjustment in the catalytic triad of lipase AK, representing a potential direction for future site-directed mutagenesis.

CuI-catalyzed synthesis of functionalized terminal allenes from 1-alkynes

Luo, Hongwen,Ma, Shengming

, p. 3041 - 3048 (2013/06/27)

Relative to our original protocol that uses CuI (0.5 equiv.), paraformaldehyde (2.5 equiv.), and dicyclohexylamine (1.8 equiv.), a facile and efficient protocol for the gram-scale synthesis of functionalized terminal allenes by using CuI (7.5-10 mol-%), p
