T. Mukaiyama et al., Diethylaluminum ethoxide mediated crossed aldol reaction of enol esters with carbonyl compounds, CHEM LETT, (9), 1999, pp. 951-952
Crossed aldol reaction of enol esters, stable carbon nucleophiles, with car
bonyl compounds is effectively performed by the promotion of diethylaluminu
m ethoxide under mild conditions. This reaction is applicable not only to s
imple enol esters but also to lactones such as alpha-angelicalactone.
