Palladium-catalyzed mono- and dicarbonylation

Propargylic compounds undergo facile palladium-catalyzed mono- and dicarbonylations, depending on the reaction conditions [9]. The carbonylation of propargylic alcohols has... 

Depending on the catalytic species, palladium-catalyzed mono- and dicarbonyl-ation of alkynes may be achieved. Monocarbonylation of acetylenic alcohols in the presence of thiourea is an elegant route to a-methylene-7-butyrolactone 202, the structure of which is widely distributed in certain natural products98,99). The synthesis of a vernolepine derivative (203) has been attempted by this method 100l Pro-...
