The synthesis of stemofurans C, L and T was achieved using organomanganese arene complexes. The critical carbon-carbon bond between the C-2 position of benzofuran and the arene was established in a regioselective manner directed by the cationic manga

The seven-step synthesis of the C3–C7 fragment from 3-furanmethanol is described. The key step is an asymmetric aldol reaction of a γ-hydroxybutenolide with the titanium enolate of an N -propionyloxazolidinone. The resulting lactone was reduced to

The Diels–Alder reaction of γ-hydroxybutenolides with dienes gave good yields of cycloadducts under thermal and Lewis acid catalyzed conditions. The application of this methodology to a more complex system was demonstrated by the synthesis of a mo

The synthesis of the all-syn C35–C39 stereopentad of etnangien has been achieved using the asymmetric aldol reaction of a γ-hydroxybutenolide (5-hydroxy-4-methylfuran-2(5H)-one) as the key step in the five-step synthesis. The reaction of the titan

The A-rings of calcitriol (1α,25-dihydroxyvitamin D(3)) and 1α-hydroxy-3-deoxyvitamin D(3) were synthesized using the furan approach. The critical steps in the synthesis of the A-ring of calcitriol involved an asymmetric carbonyl-ene reaction of 3-
