Article abstract of DOI:10.1016/S0040-4020(01)82372-3

A general asymmetric approach toward cis-epoxypolyynes is described using optically pure (2R, 3S)-5-bromo-2,3-epoxy-4-pentyn-1-ol 1a as the key intermediate. From this intermediate, the synthesis of 2 epoxy polyyne natural products was carried out in 6 steps with a 42% overall yield.
