- Studies directed toward the synthesis of martinellines : One pot synthesis of pyrroloquinolone ring system
-
The Pd-catalysed coupling between aryl iodides and 3-carbethoxy-4,5-dihydropyrroles has been described. With ortho-iodoanilines, tandem cyclisation leading to pyrroloquinolones present in martinellines, was observed.

- Process for the production of high energy materials
-
A process for the production of a high energy nitrate ester involves reacting, in an inert organic solvent, a heterocyclic compound, selected from oxiranes, oxetanes, N-substituted aziridines and N-substituted azetidines, with either N2 O4 or N2 O5, and when the compound is reacted with N2 O4, oxidizing the O- or N-nitrate substituents or substituent in the product to O- or N-nitrate substituent or substituents. The remaining ring carbon atoms on the heterocyclic compound may be substituted or unsubstituted. Preferred substituent groups for the C and/or N ring atoms on the compound include alkyl, cyanoalkyl, haloalkyl, nitroalkyl, and substituted aryl. Several novel nitrate ester are also provided, including nitrated derivatives of polybutadiene, in which between 1% and 25% of the carbon atoms in the polymer are substituted by vicinal nitrate ester (--ONO2) groups.
