4-[1-hydroxy-2- [[1-(3,4-dihydro-8- hydroxy-1-oxo-1H-2-benzopyran-3-yl)-3-methylbutyl]amino]-2-oxoethyl]-3- (acetylamino)butan-4-olide (7), led to a considerable decrease in activity. Both di- and triacetylated derivatives of 6, 4-[1-acetoxy-2 -[[1-(3,4-dihydro-8-hydroxy-1-oxo-1H-2-benzopyran-3-yl)-3-methylbutyl] amino]-2-oxoethyl]-3-(acetylamino)butan-4-olide (8) and 4-[1-acetoxy-2- [[1-(3,4- dihydro-
