(Chemical Equation Presented) Transannular PtCl2-catalyzed cycloisomerizations open a new route to cyclopropanic tricyclic systems. Ketones A or C were efficiently prepared from the same cycloundec-5-en-1-yne precursor B, depending on the subst

An eleven-membered macrocyclic bromomethyldimethylsilyl propargylic ether has been prepared in order to examine the regioselectivity of a transannular radical process. The vinyl radical intermediate appeared to follow exclusively a 6-(π-endo)endo-trig/7-(π-exo)exo-trig transcyclization course to create a 6,7-bicyclic skeleton.
