Tetracyclic Core

A rapid assembly of the tetracyclic core of marine diterpenoids related to puupehenone and kampanols by a Diels–Alder reaction of 1,3,3-trimethyl-2-vinyl-1-cyclohexene with chromones under microwave irradiation with or without TiCl4 is described.

Danishefsky's Diene

The synthesis of isoquinolinone carboxylates was performed using arecoline or its isomer N-methyl tetrahydro pyridine carboxylate with Danishefsky's diene via thermal or microwave assisted Diels-Alder reaction. The comparison of both condensation modes showed that the microwave method not only afforded higher yields of the adducts, but also lead to the formation of a new α,β-unsaturated pyridyl ketone. All structures were identified with the help of high resolution 2D NMR.Key words: Diels-Alder microwave assisted reaction, microwave synthesis, Michael, diene, isoquinoline carboxylate synthesis, Danishefsky diene synthesis, MAP Diels-Alder2.
