Total Synthesis of dl-Tazettine and 6a-Epipretazettine: A Formal Synthesis of dl-Pretazettine. Some Observations on the Relationship of 6a-Epipretazettine and Tazettine

Diels-Alder cycloaddition of dienophile 26 with diene 8 produces the protected 4-aryl-4-acylcyclohexadienone 37.This is converted in two steps to the oxidized mesembrine derivative 11.Through the novel use of trimethyl orthoformate as a C1 inte
