Cyclic Phosphine Oxides and Phosphinamides from Di-Grignard Reagents and Phosphonic Dichlorides: Modular Access to Annulated Phospholanes

The reaction between 1,4-di-Grignard reagents and phosphonous(III) dichlorides is a classical method for the direct synthesis of phospholanes. Reported here is an extension of this approach to the preparation of value-added, annulated phospholane oxides, achieved through the combination of carbocyclic-fused di-Grignard reagents and readily available phosphonic(V) dichlorides. The procedure is amenable to (benz)annulation at both the 2,3- and 3,4-positions of the phospholane ring, and a variety of aliphatic, cyclic and aryl P-electrophiles are tolerated in reasonable to excellent yields.

PRELIMINARY RESULTS IN CYCLOADDITION OF DIPHENYLNITRILIMINE TO PHOSPHINDOLE OXIDES

Diphenylnitrilimine cycloaddition reactions to two phosphindoles oxides are regiospecific ans stereospecific.The approach of the dipole occurs from the less hindered diastereotopic side of the dipolarophile.
