An efficient, unified approach to chiral, protected beta-hydroxy gamma-amin
o and alpha-hydroxy beta-amino acids derived from Boc-L-leucine has been ac
complished on the basis of the oxazaborolidine-controlled, stereoselective
reduction of 1-trialkylsilyl acetylenic ketones; stereoselectivity in the r
eduction step has shown strong dependence upon C(1) substitution.
