3-Phenylthio-4,4-diethoxycarbonyl-azetidin-2-ones 8 have been conveniently synthesised by reacting 2-chlorophenylthioacetyl chloride 5 with aryl substituted aminomalonates 7 under mild basic conditions. Alternatively, C-3 alkylation of azetidin-2-one usin
Synthesis of a Novel Tetracyclic Acridine. A Sulphoxide-based Route to the 1,2,3,4-Tetrahydrobenzophenanthroline Ring System

The ambit of the classical acridine synthesis, via acid-mediated cyclisation of 2-oxodiphenylamines, has been extended to include a sulphoxide-containing precursor.This adaption produced the tetracyclic system of 1 in a single step from 25.
