Abstract

Vinylgermanes (1), bearing a hydroxy group, were efficiently cyclized to 2-(germylmethyl)tetrahydrofurans (2) in the presence of an acid catalyst. The intra-molecular addition of the hydroxy group proceeded in a stereospecific syn mode. The acid-catalyzed cyclization of α-alkyl-substituted vinylgermanes (8) gave 1,2-germyl-migration products (9).
