High diastereoface selection in an ester enolate addition to .alpha.-alkoxy aldehydes: stereoselective synthesis of .alpha.-methylene-.beta.-hydroxy-.gamma.-alkoxy esters
The Reformatsky-type condensation between methyl and t-butyl 3-(N,N-dimethylamino)propionates (9) and (10) with α-alkoxyaldehydes, which has been studied on varying the protective group of the aldehyde, proceeds with good diastereoselectivity.
