Selective C- tert -butoxycarbonylation using di- tert -butyl dicarbonate for the synthesis of multifunctional carbon compounds

The reaction of di-tert-butyl dicarbonate (Boc2O) in the presence of the acylation catalyst 4-dimethylaminopyridine (DMAP) was examined with N-Boc or N-acyl cyanoglycinate. The couple Boc2O/DMAP was found to act as an efficient agent for selective C-tert-butoxycarbonylation affording multifunctional carbon compounds.

Organocatalytic asymmetric synthesis of versatile γ-lactams

A goodstarting point: Optically pure glactams have been prepared by organocatalytic enantioselective vinylic substitution. The parent lactam structure allows logical and systematic introduction of functionality around the periphery to access new derivativ

Electrophilic amination of enolates with oxaziridines: Effects of oxaziridine structure and reaction conditions

A range of N-alkoxycarbonyl- and N-carboxamido-oxaziridines has been prepared to test the effects of oxaziridine structure on yields of enolate amination product. Side-products arising from reaction of aldehyde-derived oxaziridines with base were identified, while a ketone-derived oxaziridine afforded moderate yields of amination product with stabilised carbanions.
