The cyclization of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with oxalyl chloride afforded functionalized gamma-alkylidene-alpha-hydroxybutenolides, which were transformed into cis-configured gamma-lactones by diastereoselective hydrogenation.((C) Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002).
