for the synthesis of various quinone-amino acid hybrids through ethylene cross-enyne metathesis and Diels-Alderreaction as keysteps is described. A library of comformationally constrained quinone-based phenylalanine derivatives and dicarba analogs of cystine have been generated starting from a common precursor using Grubbs' catalysts. This methodology has also been extended for the synthesis of fullerene-based
