A sensitive nonradioisotopic method is reported for measuring microsomal lauric acid omega-hydroxylation activity. The assay is based upon separation and detection of 12-hydroxylauric acid formed by means of high-performance liquid chromatography following fluorescence labeling of the carboxyl group with 3-bromomethyl-7-methoxy-1,4-benzoxazin-2-one

An efficient direct one-pot glycosylation method with anomeric hydroxy sugars as glycosyl donors employing phthalic anhydride and triflic anhydride as activating agents has been developed. Thus, highly stereoselective beta-mannopyranosylations were achieved by the reaction of 2,3-di-O-benzyl-4,6-O-benzylidene-D-mannopyranose (2) with phthalic anhydride
