摘要
(Chemical Equation Presented) Simply complex: An organocatalytic tandem Michael/Morita-Baylis-Hillman reaction has been developed in which secondary amine catalysts allow for a very selective, scalable synthesis of highly substituted optically active cyclohexanones (see scheme, TMS = trimethylsilyl). Mechanistic studies indicate an active role of the secondary amine catalyst in the Morita-Baylis-Hillman reaction. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
