Article abstract of DOI:10.1016/S0040-4039(00)86723-4

Reactions of 3-nitro-2-methoxybenzaldehydes with the boron enolate of a chiral propionyl oxazolidone has been demonstrated to yield poor diastereoselection in the presence of i-Pr2NEt as base whereas the use of Et3N results in 98percent diastereoselection
