First total synthesis of heterocurvistone
Villecco, Margarita B.,Catalán, César A. N.,Joseph-Nathan, Pedro
, p. 959 - 963 (2007/10/03)
The sesquiterpene ketone (±)-heterocurvistone was synthesized in eight steps and 12% overall yield from known methyl R-(+)-3-(4-methyl-3-cyclohexen-1-yl)-3-butenoate, readily available from R-(+)-limonene. The key synthetic step is an oxymercuration-induced cyclization.
