Abstract

Diastereoselective asymmetric intramolecular Diels-Alder reaction of 5,5-(trimethylenedithio)-2(E),7(E),9-decatrienoyl amides (13a-e) having various chiral auxiliaries was performed to give optically active trans-hydrindanes, which would be an important intermediate for a total synthesis of plakotenin (1), was described. In the several chiral auxiliaries, Saigo's oxazolidinone was found to give trans-hydrindane (15a) in the highest stereoselectivity (96% e.e.), after conversion to benzyl ester.
