Abstract

The reaction of 2-imino-1, 2-diphenylethanone with sodium in ether and subsequent addition of carbon disulfide or ethyl chloroformate resulted in the formation of 3, 4, 5- trisubstituted 4-oxazoline-2-thiones and 2-ones, respectively. 1, 4-Oxazonines and 1, 4- oxazocines were also synthesised from the reaction of 2-imino-1, 2-diphenylethanone with sodium in THF followed by addition of dihaloalkanes.
