✦ Synopsis

1998 carboxylic acid esters carboxylic acid esters (acyclic compounds) P 0360 21 -078 A Novel Synthesis of 1,3-Diol Diesters by the Reaction of Aldehydes with Oxime Esters Catalyzed by Samarium Complex.

-In connection with an earlier study the title reaction to esters such as (III) is developed. It is noteworthy that no reaction is observed in the presence of SmI 2 , SmI 3 and Sm(OTf) 3 . Other complexes such as Cp 2 Yb(thf) 2 are less effective. In the reaction with vinyl acetate (IV) the presence of (II) is important for the yield (17% yield in the absence of (II)). Mechanistical aspects are discussed.
