Abstract

A simple and convenient method for the construction of substituted cycloheptenones from 1-bromoocta-1,7-diene-3-ols has been developed. The reaction involves Pd(0)-catalyzed intramolecular 7-exo-trig cyclization followed by Pd(ii)-catalyzed oxidation of cyclic alcohol. The course of the reaction pathway has been evaluated using DFT calculations. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: A palladium catalyzed domino intermolecular Suzuki followed by intramolecular Heck coupling is described. This strategy afforded a novel and convenient synthesis of various 9-fluorenylidene derivatives in one-pot under relatively mild reaction condition. [Copyright &y& Elsevier]
