title: Gold catalysis: regio- and stereoselective total synthesis of xyloketals D and G and the related natural product alboatrin.
abstract: A new and efficient one-pot desilylation-gold-catalyzed cycloisomerization of alkynes containing a silyl-protected phenolic -OH and a free alcoholic -OH unit leads selectively to the formation of tetrahydrofuranobenzopyran ring system. This approach has been used for the regio- and stereoselective synthesis of xyloketal D, xyloketal G, and the related natural product alboatrin.
