DESCRIPTION:Carbocyclizations\, annulation processes involving carbon-carbo
 n bond formation via carbometalation\, constitute an extremely important a
 nd useful class of reaction for the syntheses of carbocyclic and heterocyc
 lic compounds. We have recently developed a number of selective palladium-
 catalyzed oxidative carbocyclizations of unsaturated systems often involvi
 ng the use of molecular oxygen as the oxidant in a biomimetic approach. Mi
 ld oxidative C-C bond formation under aerobic conditions can be achieved v
 ia this approach.\n\nWe have developed oxidative borylative and arylative 
 carbocyclization of en­allenes\, allenynes\, and bis-allenes as well as  C
 -H activation/carbocyclization of arylallenes. For some recent application
 s see ref 1-5.\n\nIn another approach to biomimetic catalysis\, enzymes ha
 ve been combined with racemization catalysts for dynamic kinetic resolutio
 n.6 An example of the latter approach is the development of a biomimetic h
 ybrid catalyst that works as an artificial metalloenzyme.7\n\n1. T. Jiang\
