REACTIONS OF CYCLIC AZA-YLIDES WITH β-DICARBONYL COMPOUNDS
摘要:
The reactions of five- and six-membered cyclic iminophosphoranes, 3 and 4, with P-dicarbonyl compounds gave enamino phosphine oxide derivatives 5a-h in good yields. Compounds 5b and 5e were stereoselectively converted to 1,6- and 1,7-diene 9a and 9b.
