1β,6β-Epoxy-hexahydrocannabinol acetate (1) in the presence of borontrifluoride rearranged to 6-oxo-hexahydrocannabinol acetate (3b) and to the aldehyde (4). Hydroboration of Δ6-THC gave the 6-hydroxy hexahydrocannabinols 5a and 8a. The latter was converted into Δ5-THC (11). This THC isomer shows no cannabis-type activity in rhesus monkeys.
