Abstract
Abstract A number of 4''-acyl derivatives of tylosin and acetyltylosin which are prepared by first protectively acylating at the 2'-hydroxyl group of tylosin or acetyltylosin, secondly at the 4'''-hydroxyl group thereof, thirdly at the 4''-hydroxyl group thereof and finally deacylating the 2'- and 4'''-acyl groups to produce new 4''-acyl derivatives of tylosin or acetyltylosin which effect high blood level compared to those tylosin derivatives heretofore are disclosed.
