Abstract
Addressing the challenge of constructing multi-substituted dihydropyrans, we present an efficient synthesis method for oxygen-containing heterocycles. Using thiones and metal carbenes, we employed xanthate and triazole to intramolecularly synthesize dihydropyran or dihydrofuran compounds. 1,2-Hydride migration was inhibited, and thiodihydropyrans were obtained in excellent yields. A mechanism proceeding through a Rh-carbene intermediate is proposed for the multi-substituted dihydropyrans synthesis.

Abstract
Asymmetric construction of C-S bond through transition-metal catalysis is a challenging subject. By using chiral diene as ligand, we have developed the first rhodium(I)-catalyzed asymmetric carbene insertion approach for C-S...
