The High Pressure Diels-Alder Reactions of Quinone-mono-ketals. -Simple quinone-mono-ketals react with nonactivated dienes at high pressure to yield the corresponding adducts. Treatment of these adducts with catalytic acid forms the aromatized products, i.e. the annulated benzenes or naphthalenes.
## Absbxxct: Diels-Alder reaction of 2-methoxycarbonyl-gquinone 2 with Ll_-glucose based dienes 4 (a-h) -7furnished cis-adducts 10 (a-h) in a stereo-and regiospecific manner. Chemical transformation of 10 affoxd K-E. cornj&ds G 13 and G are key intermediates in the proposed synthesis of forskolin.
