摘要

The title synthesis was achieved by featuring diastereoface-selective cyclopropanation of (4R, 5S)-4, 5-diphenyl-3-vinyl-2-oxazolidinone and its related compounds, the chiral conformationally rigid N-vinylcarbamates, with zinc-monofluorocarbenoid, followed by hydrogenolysis of the major addition products. The diastereoface-selectivity of the cyclopropanation could be explained by the most stable conformation of 3-vinyl-2- ...
