ABSTRACT Intermediates, and processes for their preparation, usful in the preparation of 3-(N-aryl-N-acylamino)-gamma-butyrothiolactone fungicides. The intermediates are prepared by cleaving the corresponding arylamino-gamma- lactone with a thiolate salt to yield the corresponding arylamino-thiol- alkane carboxylate salt, hydrolyzing the salt and then acylating to yield the desired. N-acyl-N-arylamino intermediate product. This intermediate may then be cyclized to yield the fungicide named above.
