More Information
Summary:3-(N-aryl-N-acylamino)gamma- butyrothiolactones having fungicidal activity are prepared by a process which comprises in a preferred embodiment cleaving the corresponding arylamino-gamma- lactone with a thiolate salt to yield the corresponding arylamino-thiolalkane carboxylate salt; hydrolyzing the salt and then acylating the resulting acid to yield the corresponding N-acyl-N- aryl-amino product. This product is then cyclized to yield the required compound. Alternatively, the order of the acylation and cyclization can be reversed. Also novel compounds of the formula wherein Ar is optionally substituted aryl, R is alkyl, alkenyl or aryl-alkyl, R are various substituents, R is H, Cl, Br, I, alkyl or optionally substituted phenyl and R is H or wherein R is as defined above.
