39886-80-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39886-80-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,8 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 39886-80:
(7*3)+(6*9)+(5*8)+(4*8)+(3*6)+(2*8)+(1*0)=181
181 % 10 = 1
So 39886-80-1 is a valid CAS Registry Number.

New scalable and eco-friendly synthesis of gingerols

Vijendra Kumar,Srinivas,Bettadaiah

, p. 2993 - 2995 (2012/07/31)

Synthesis of 6-gingerol and its congeners 7- and 9-gingerols has been achieved from eugenol by a new scalable and eco-friendly protocol. The key steps are functionalization of eugenol to the nitro compound and its reaction under optimized condition with terminal alkenes to afford intermediate isoxazolines. The latter on catalytic hydrogenation in presence of Raney nickel afford corresponding gingerols in good yields.

The optically active Lewis acid 6 has been prepared and used in the enantioselective addition of enolsilanes and Me3SiCN to aldehydes.

Asymmetric Synthesis of a β-Ketol Moiety via 3,5-Disubstitute Isoxazoles: Application to (+)-(S)--Gingerol

Giovanni, Baraldi Pier,Fabio, Moroder,Piero, Pollini Gian,Daniele, Simoni,Achille, Barco,Simonetta, Benetti

, p. 2983 - 2988 (2007/10/02)

A new synthesis of (+/-)--gingerol (13), (+)-(S)--gingerol, and (+)-methyl--gingerol (12c) using 3,5-disubstituted isoxazoles as masked β-ketols, is described.Reductive fission of the labile N-O bond of the isoxazoles (8a) and (8b) gave the enami
