New cyclization reactions in organic syntheses*
Department of Chemistry, State University of New York
at Stony Brook, Stony Brook, NY 11794-3400, USA
Abstract: Recent development in the transition metal-catalyzed
cyclization reactions for organic syntheses in the author's laboratories
is summarized, which includes (i) novel silylcarbocyclizations (SiCaCs)
and carbonylative carbotricyclizations, (ii) intramolecular silylformylations
and desymmerization of siloxydiynes by sequential double silylformylation,
(iii) efficient total synthesis of (+)-prosopinine, (iv) enantioselective
desymmetrization of aminodienes, and (iv) new and efficient routes to
1-azabicyclo[x.y.0]alkane amino acids. All these processes are catalyzed
by Rh or RhCo complexes, and useful for rapid and efficient construction
of a variety of heterocyclic and carbocyclic compounds. Mechanisms of
these new carbocyclization and cyclohydrocarbonylation reactions are
