Synthesis of leprapinic acid, calycine and analogues by sequential "[3+2] cyclization/suzuki/lactonization" reactions

Calycine and analogues were prepared on the basis of Suzuki cross-coupling reactions of γ-alkylidene-α-hydroxybutenolides - readily available by cyclization of 1,3-dicarbonyl dianions or 1,3-bis(silyl enol ether)s with oxalyl derivatives - and subsequent boron tribromide-mediated lactonization. Leprapinic acid was prepared by chemoselective boron tribromide-mediated deprotection of permethylated leprapinic acid. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
