title: Versatile synthesis of the C3-C14 domain of 7-deoxyokadaic acid.
abstract: Described is a flexible synthesis of the C3-C14 domain of 7-deoxyokadaic acid that is amenable to facile structural diversification. Treatment of ynone 10 under acidic conditions led to net bis-conjugate addition of the latent diol to give the thermodynamically favored spiroketal 27, a versatile intermediate, en route to 7-deoxyokadaic acid and analogs.
