The magnesiumchloride catalyzed anti-aldol reaction of phenyl acetate derived oxazolidinones proceeds readily with enolizable L-threose derivative 8 to provide anti-aldol adducts in high yields and with very high diastereoselectivities. The reaction is also efficient with aromatic aldehydes and provides slightly lower diastereoselectivities. This extension
