We have developed an NMR chemical shift prediction system that enables high throughput automatic grading of NMR spectra. In support of high throughput synthetic efforts for our drug discovery program, a rapid and accurate analysis for identity was ne

Analogs of 3-deoxy- d - manno -octulosonic acid (Kdo) having the β-anomeric hydroxyl group replaced by a substituted-methyl group were prepared from Kdo. The substituted-methyl groups were derived from the carboxyl group of Kdo, whereas the carboxyl

Selective C-8 modifications of 2,6-anhydro-3-deoxy-D-glycero-D-talo-octonic acid ("2,3-dideoxy-beta-D-manno-2-octulosonic acid", 1a) were effected via the protected 8-hydroxy derivatives 2d and 2e. Swern oxidation of 2d and 2e gave the aldehydes 3a a

A glucuronoarabinoxylan in which about six of every seven xylosyl residues were substituted with terminal arabinofuranosyl and glucosyluronic groups was extracted from developing maize coleoptiles with dilute alkali and purified by gel-permeation chr

The Friedel-Crafts reactions of optically active phenyloxirane with toluene and anisole were examined for stereospecificity. The enantiomeric ratios of the diarylethanol products were determined and compared to those of the same products obtained fro
