Process and intermediates for chiral epoxides
摘要:
Chiral epoxybutyrates are prepared in high yield from novel dihydro-3R-substituted sulfonyloxy-4R-hydroxy-2-(3H)furanones via based catalyzed alcoholysis. The product chiral epoxy butyrates are useful intermediates for the synthesis of 1-carba-1-dethia cephem antibiotics.
