, p. 3911 - 3914 (2007/10/02)
Syn acyclic homoaldol products have been prepared by the conjugate addition reaction of α-alkoxyorganocuprates to enals.Selectivities of up to > 250:1 have been obtained.
REACTION OF DITHIO-SUBSTITUTED CINNAMYLLITHIUM WITH CARBONYL COMPOUNDS: A TEST OF THE HSAB PRINCIPLE
Fang, Jim-Min,Chen, Ming-Yi,Yang, Wen-Jin
, p. 5937 - 5938 (2007/10/02)
By mediation of BF3.Et2O, dithio substituted cinnamyllithium 2 reacted predominantly at the α-site with carbonyl compounds.No selectivity was found when the reaction was performed in the absence of BF3.Et2O.

Carbonyl addition compounds of diethyl trimethylsilyl phosphite (DTMSP) with aldehydes were converted, by treatment with lithium diisopropylamide (LDA) followed by the successive alkylation and alkaline hydrolysis, to carbonyl derivatives involving aldehydes, unsymmetrical ketones, β,γ-unsaturated ketones, and carboxylic acids. β-Substituted carboxylic esters and γ-substituted lactones were prepared by use of the carbonyl addition compounds of DTMSP with α,β-unsaturated aldehydes.
