Significance

The authors report a one-pot strategy where alkene cross-metathesis is coupled to oxonium ylide formation and subsequent [2,3]-sigmatropic rearrangement. The strategy was successfully applied to the divergent synthesis of dihydrofuranones and anti-HIV agent hyperlactone C. This is an advancement from previous work where alkene cross-metathesis was coupled to carbonyl ylide formation and subsequent 1,3-dipolar cycloaddition (Adv. Synth. Catal. 2006, 348, 2509).
