title: Double diastereoselection in anti aldol reactions mediated by dicyclohexylchloroborane between an L-erythrulose derivative and chiral aldehydes.
abstract: Anti aldol reactions of an l-erythrulose derivative with several α-chiral aldehydes mediated by dicyclohexylboron chloride are examined. Good yields and stereoselectivities are observed. The results are best explained when the reactions are assumed to occur via boat-like transition states with minimization of 1,3-allylic strain and avoidance of syn pentane interactions.
