Abstract
An unexpected synthesis of an alpha, beta, gamma, delta-unsaturated ketone, which embodies a new type of oxy-carbon cyclic structure, was achieved, wh ile we tried to construct the taxane CB-ring system. Also, a series of abno rmal reaction phenomena was found to be related to the formation and reacti on of seven membered cyclic benzylidene acetal.
