SYNTHESES AND METAL MEDIATED REACTION CHEMISTRY OF 2-SILYL-1,3-DIENES
… Diels-Alder reactions and subsequent Hiyama-Denmark and Negishi cross couplings to make highly substituted cyclohexenoids with controlled relative and absolute stereochemistries. Diterpenoids containing the clerodane carbon skeleton are prevalent as secondary metabolites. Synthetic …

1. Reinvestigation of a catalytic, enantioselective alkene dibromination and chlorohydroxylation, 2. Double cross-coupling reactions of siloxaborolates, 3. The enantioselective synthesis of 3-substituted morpholines using computer-guided catalyst design
… proceeded with high yields but the second, Hiyama-Denmark reaction proved troublesome for coupling with electron-rich aryl bromides, providing only low yields of the desired teraryls. A four-factor DoE study was undertaken to attempt to identify conditions to allow a more general scope for …
