Reactions of readily available and stable 1-(α-alkoxyalkyl)benzotriazoles type 9a,b and 10a-d with a variety of silyl enol ethers 11 or 1,3-dicarbonyl compounds 13 give the expected ketones 12a-l (60-92%), β-keto esters 14a,b (62-67%), and malonates 14c,d
CROWN ETHER CATALYSIS IN THE SYNTHESIS OF CYANOHYDRIN DERIVATIVES
Chenevert, Robert,Plante, Raymond,Voyer, Normand
, p. 403 - 410 (2007/10/02)
Carbonyl compounds react with cyanide ion under phase transfer catalysis (18-crown-6) to give cyanohydrin anions which are trapped by acid chlorides, anhydrides or alkylating agents to give cyanohydrin derivatives.
