摘要:
Each of the four enantiomerically pure tetrahydropyran linalool oxides was prepared by separate enantioselective Sharpless dihydroxylation of (R)- or (S)-linalyl acetate with AD-mix-alpha or AD-mix-beta, followed by a completely stereoselective N-phenylselenophthalimide cyclization of an intermediate allylic alcohol.
