Abstract

A new atom-economical synthetic strategy for the synthesis of furans emerges from j3, y- unsaturated ketones which are readily available from, acetylenes and allyl alcohols by simple additions in the presence of a ruthenium catalyst. Dihydroxylation using catalytic osmium tetraoxide creates a diol that is remarkably prone to cyclize to furans in the presence of an acid catalyst. The novelty of this synthesis lies in the overall strategy whereby furans ...
