Abstract
In the presence of triethylamine, Diels-Alder reaction, involving decarboxylation-oxidation reaction of 3-hydroxy-2-pyrones with 1,4-benzoquinones gave 5-hydroxy-1,4-naphthoquinone derivatives in excellent to reasonable yields.
Key words
Diels-Alder reaction - oxidations - quinones - polycycles - tandem reaction
