Abstract

1, 3-OXAZOLINES REPRESENT A SIMPLE HETEROCYCLIC FRAME WHICH HAS BEEN SCARCELY EXPLORED COMPARED TO THE NON-AROMATIC COUNTERPART 1, 3-OXAZOLIDINE STRUCTURE. SURPRISINGLY FOR THIS SIMPLE HETEROCYCLE, ONLY BASIC STRUCTURES RELATED TO ACETOL HAVE BEEN CONVERTED INTO 1, 3-OXAZOLINE-2-THIONES. SYNTHESIS OF 1, 3-OXAZOLINES WERE REPORTED USING EITHER CONDENSATION OF THIOCYANIC ACID OR ISOTHIOCYANATES WITH AN A-HYDROXYCARBONYL, OR CONDENSATION OF THIOPHOSGEN WITH AN AMINOKETONE. THE POSSIBLE BALANCE OF REACTIVITY OF A-HYDROXYCARBONYL SYSTEMS WITH THIOCYANIC ACID TOWARD THE FORMATION OF 1, 3-OXAZOLINE HAVE BEEN RECENTLY REPORTED.THUS, THE REACTION OF AMMONIUM THIOCYANATE1, ACID CHLORIDES 2, ALKYLBROMIDE 3 IN THE PRESENCE OF N-METHYLIMIDAZOLE UNDER SOLVENT-FREE CONDITIONS, PRODUCED 1, 3-OXAZOLES 4 IN GOOD YIELDS.
