These compounds are thus the products in the Dakin-West reaction and (*) Fukuyama coupling, and both reactants and products in the Robinson annulation.
Equal amounts of two isomers of one of these compounds are made by a reaction in which DMAP or pyradine react with an amino acid. These compounds are the major product in the reaction of an organozinc halide and thioester under palladium catalysis. Two of these, one equipped with methyl and vynil groups, can react through two addition reactions and a dehydration to produce a third one of these that is cyclic and alpha, beta unsaturated. These compounds are thus the products in the Dakin-West reaction and (*) Fukuyama coupling, and both reactants and products in the Robinson annulation. For 10 points, name this functional group consisting of two carbon atoms bonded a carbon-double-bond-oxygen group.
