Method for the preparation of 2,3-dimethyl aziridine
Abstract
Abstract THIS INVENTION INVOLVES THE SYNTHESIS OF 2,3-DIMETHYL AZIRIDINE IN BOTH ITS CIS AND TRANS ISOMERIC FORMS. SYNTHESIS IS EFFECTED BY TREATING THE APPROPRIATE ISOMERIC FORM OF 2-BUTENE. TREATMENT IS CARRIED OUT BY A FOUR STEP PROCESS RESULTING IN THE FORMATION OF THE CORRESPONDING CIS-2,3DIMETHYL AZIRIDINE COMPOUND OR THE TRANS-2,3-DIMETHYL AZIRIDINE COMPOUND. IN THE FIRST STEP OF THE PROCESS, 2-BUTENE IS EPOXIDIZED WITH PERACETIC ACID. THE RESULTING EPOXIDE IS THEN CONVERTED TO AN AMINO ALCOHOL BY TREATMENT WITH AMMONIA. IN THE THIRD STEP, AN INNER SALT IS FORMED BY REACTING THE AMINO ALCOHOL WITH CHLOROSULFONIC ACID. FINALLY, THE INNER SALT IS TREATED WITH SODIUM HYDROXIDE TO PRODUCE THE AZIRIDINE COMPOUND OF THIS INVENTION.
