3-triazole (14), 3-phenylisoxazole (15), 3-phenylisothiazole (16), 2-phenylthiazole (17), and 2-phenyloxazole (18). None of the bis(carbamates) prepared was active against murine P388 lymphocytic leukemia. Pyrrole bis(carbamates) 20 and 21, which exhibited antileukemic activity, also showed reactivity toward 4-(p-nitrobenzyl)pyridine while the inactive bis(carbamates) were unreactive in the 4-(p-nitrobenzyl)pyridine

R,S-(±)-Dimethyl(1-methyl-2-oxo-2-phenylethyl)sulphoniumbromide (3a), obtained from 1-phenylpropanone by bromination with t-buty bromide–dimethyl sulphoxide and further reaction with dimethyl sulphide, undergoes spontaneousresolution of its two enantiomers upon crystallization, as demonstrated by a single crystal X-ray analysis and assignment of absoluteconfiguration (R).
