Abstract

Abstract Vinyl-, alkyl-and π-allyl-palladium species arising from regiospecific palladium catalysed 5-or 6-exo-dig or-trig cyclisations onto proximate alkynes, alkenes or dienes can be intercepted stereospecifically by organozinc or organo boron reagents leading to carbo- and hetero-cyclic compounds in moderate to good yield.
