Jansen, Ben J. M.,Schepers, Gert C.,Groot, Aede de
, p. 2773 - 2776 (2007/10/02)
The trans-syn-cis tricyclic system, present in (+/-)-9βH-pimara-7,19-diene (8) was formed via a Diels-Alder reaction of enone aldehyde 2 with 2-(tert-butyldimethylsilyloxy)-3-methyl-1,3-butadiene.The resulting regiospecific silyl enol ether was deformylat
