Mixedanhydrides of carboxylicacids have been selectively reduced to alcohols with borohydride exchange resin–nickel acetate under mild conditions and in good yields.
Two series of sulfonylureasderivatives including 24 compounds ( 4 , 7 , 5a – 5o , 8a – 8h ), among them 17 newderivatives, have been synthesized and evaluated for their α -glucosidase inhibitory activity. Compounds 5c , 5h and 8e showed significant in vitro α -glucosidase inhibition with IC 50 values of 5.58, 79.85 and 213.36 µ m , respectively, comparing with the standard compounds acarbose (IC
