For the first time an environmentally benign solvent/catalyst-free protocol for the synthesis of a variety of N-substituted phthalimides is submitted. It involves a one-pot coupling of nascent phosphazene generated in situ with phthalic anhydride. The protocol is novel in (1) avoiding toxic solvents, (2) no catalyst is employed and (3) no isophthalimide is formed as noted in the prevailing solution phase/catalysed methodology.

Benzylation of chiral esters of N-acyglycines using various bases and additives was examined.No C-alkylation was observed with one equivalent of base.Diastereoselectivities were dependent on the amount of additive, the nature of the N-acyl group, and the chiral ester.A model to account for the degree and sense of the stereoselectivity is proposed.

Photochemical reactions of phthalimides having various carbonyl functions (amides 3a-h, esters 11,14, and thioester 17) in their N-alkyl side chain are studied.By irradiation fused hydropyrazines (4a, e, g, h) and hydro-1,4-diazepines (4b, f) were formed from amide derivatives 3 through photocyclization, whereas the esters 11,14 showed addition and reduction reactions of the imide carbonyl group, and thioester 17 showed Norrish-type I reaction of the thioester moiety, in each case, however, without yielding cyclized products.
