55359-62-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55359-62-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,5 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55359-62:
(7*5)+(6*5)+(5*3)+(4*5)+(3*9)+(2*6)+(1*2)=141
141 % 10 = 1
So 55359-62-1 is a valid CAS Registry Number.

Rhodium-catalyzed intramolecular hydroacylation of 1,2-disubstituted alkenes for the synthesis of 2-substituted indanones

Yuan, Jing,Liu, Chong,Chen, Yan,Zhang, Zhenfeng,Yan, Deyue,Zhang, Wanbin

, p. 269 - 277 (2018/12/05)

The intramolecular hydroacylation of 1,2-disubstituted alkenes was considered to be a challenging task due to the side reactions resulted from the lack of additional substituent at 1-position and the low activity caused by the steric hindrance of substituent at 2-position, and an asymmetric version has not been considered possible due to problems associated with the racemization of the products. We have partially solved these problems. Catalyzed by an activated diphosphine-Rh complex and reacted in a selected dihalogenated solvent, the intramolecular hydroacylation of o-(2-arylvinyl)benzaldehydes provided the corresponding 2-aryl-1-indanones in high yields, and its asymmetric variant using o-(2-alkylvinyl)benzaldehydes afforded chiral 2-alkyl-1-indanones in high yields and with moderate enantioselectivities.
