Abstract

A concise stereoselective total synthesis of the naturally occurring styryl lactone 8-methoxygoniodiol in five simple steps from readily available inexpensive trans-cinnamaldehyde is described. The efficient synthesis features a successful protecting-group-free strategy, with desirable step- and atom-economy. The synthetic strategy relies on a Maruoka asymmetric allylation, an epoxidation, a ring-closing metathesis, and a stereoselective epoxide ring opening as key steps.
