Various oxazolidines prepared in two steps from (R)-phenylglycinol react at 0 °C with dialkylalkynylalane-triethylamine complexes in the presence of trimethylaluminum in high yield and diastereoselectivity. Enantiomerically pure primary α-substituted propargylamines can be easily obtained in two steps after removal of ferrocenylmethyl protective group under smooth acidic conditions and oxidative cleavage of the chiral appendage.
Asymmetric synthesis of α-amino phosphonic acids by diastereoselective addition of trimethyl phosphite onto chiral oxazolidines

A simple and general asymmetric synthesis of α-amino phosphonic acids is described. The method involves the highly selective addition of trialkyl phosphite onto various chiral oxazolidines. Oxazaphosphorinanes thus obtained with an excellent diastereoselectivity furnish the corresponding (S)-α-substituted amino phosphonic acids in good overall yields and high ee (77→97%) after simple deprotection.
