Pauson-khand reaction of allenic hydrocarbons: Synthesis of 4-alkylidenecyclopentenones

Antras, Frederic,Laurent, Stephane,Ahmar, Mohammed,Chermette, Henry,Cazes, Bernard

experimental part, p. 3312 - 3336 (2010/09/04)

The carbonyldicobalt-mediated alkyne/allene/CO cocyclization gives 4-alkylidenecyclopentenones as the major [2+2+1] cycloadducts. The regio- and stereoselectivities depend mainly on the substitution pattern of both the alkyne and the allenic moieties, whi
