Abstract / Bemerkung
Sunthesis and diastereoselective Diels-Alder reactions of new spirocyclic chiral dienes are reported. Starting with diketene and (-)-menthone (1), we prepared the diastereomeric diketene-methone adducts 2 and 3. Further derivatization and olefination afforded four chiral dienes 12-15. Diastereoselective Diels-Alder reactions of these dienes with N-phenylmaleimide (NPM) under high-pressure conditions yielded the corresponding cycloadducts 16-19. Olefination of 6-diethylphosphonomethyl-2,2-dimethyl-1,3-dioxin-4-one 8 with formaldehyde led to unexpected compounds 9-11 resulting form the originally formed olefination product.
