(Z)-1,2,3,4-tetraboryl-2-butene: A reagent for stereoselective one-pot triple aldehyde addition
(Z)-1,2,3,4-Tetraboryl-2-butene reacted with three molecules of 2,3-dialkylidene-1,5-alkanediol as a single stereoisomer. Preparation and triple addition of the butene can be effected in a single operation.
