SCHEME 6.96 Pd-catalyzed cyclization reaction of 2,3-allenoic acids with 1,5-bisallene. [Pg.275]

In 2010, Lian and Ma combined one molecule of 1,5-bisallene 381 with two molecules of 2,3-aUenoic acids 346 and developed an unexpected sandwich type of triple cyclization with excellent stereoselectivity. A possible mechanism involving sequential highly stereoselective anh-oxopalladation, intermolecular carbopalladation, cyclic [Pg.275]
