A kinetic resolution of a-allenic alcohols is realized through chiral silver phosphate-catalyzed cycloisomerization with high stereoselectivity (selectivity factor up to 189) and tolerance of a variety of functional groups. A mechanistic model is proposed to interpret the origin of the high stereoselectivity and broad substrate scope.

The unprecedented Trametes versicolor laccase/TEMPO-catalyzed aromatization of 2,5-dihydrofurans to furans is described. A variety of furan derivatives have been synthesized in moderate to high conversions (21–99%) and yields (20–76%) under mild reaction conditions. This work reveals the aromatization ability of the Trametes versicolor laccase/TEMPO system in synthesizing oxygen-containing heterocycles
