Facial selectivity in the 4 + 2 reactions of a diene derived from carvone
The facial selectivities of cyclohexadienes bearing isopropenyl and isopropyl groups as plane-nonsymmetric substituents were assessed in 4 + 2 reactions with N-phenylmaleimide, tetracyanoethylene and 4-phenyl-1,2,4- ... -
Synthetic studies toward the kempane diterpenes. Construction of a key tricyclic intermediate
A synthetic sequence is described for construction of the tricyclic portion (35) of kempane diterpenes. The central stereochemistry was established by a Diels-Alder addition of 2,6-dimethyl-para-benzoquinone to a 5-membered, ... -
Vinylogous anionic processes in the formation and interconversion of tetracyclic ring systems
Tandem oxy-Cope and transannular vinylogous aldol reactions and/or vinylogous retro-aldol, conjugate addition, and transannular vinylogous aldol reactions transformed some tricyclic vinyl enones into fused tetracycles under ...
