Calculate Digit Verification of CAS Registry Number 863288-39:
(8*8)+(7*6)+(6*3)+(5*2)+(4*8)+(3*8)+(2*3)+(1*9)=205
205 % 10 = 5

, p. 111 - 116 (2021/09/28)

(E)-Methyl/ethyl-3-(2-hydroxyphenyl)acrylates 3a-x have been prepared by the reaction of salicylaldehydes 1a-l with Wittig reagents such as methyl (triphenylphosphoranylidene)acetate 2a and ethyl (triphenylphosphoranylidene)acetate 2b in dry DCM at room t

One-pot synthesis of ortho-hydroxycinnamate esters

Anwar, Hany F.,Skatteb?l, Lars,Skramstad, Jan,Hansen, Trond Vidar

, p. 5285 - 5287 (2007/10/03)

Phenols are converted to salicylaldehydes with paraformaldehyde, MgCl 2-Et3N in THF, and subsequent treatment with methyl (triphenylphosphoranylidene)acetate gave the corresponding methyl ortho-hydroxycinnamate derivatives. The sequence is conveniently carried out as a one-pot procedure.
