Conformations of three derivatives of 2-C: l-Z%carbonyl-2-deoxy-o-glycopyranosylamines were investigated in the solid state, by use of X-ray. Quantitative conformational analysis (asymmetry parameters and puckering parameters), applied to the ring system in six crystallographically determined struct

## Abstract A rapid chemical synthesis of 2‐[__carbonyl‐^11^C__]acetamido‐2‐deoxy‐D‐glucopyranose (__N__‐[__carbonyl__‐^11^C]acetyl‐D‐glucosamine) starting from [^11^C]carbon dioxide is described. The total time required for the synthesis, the radiochemical yield, and purity of the titled sugar are
Recently, we reported that the unstable [2 + 2lcycloadducts (1) of tosyl [1,2] or trichloroacetyl [3,4] isocyanate and glycals, upon treatment with alcohols or water, underwent rapid opening of the four-membered ring at the anomeric carbon atom to afford glycosides having alkoxyl and carbamoyl funct
## Abstract A convenient method for the synthesis of ^18^F‐2‐deoxy‐2‐fluoro‐D‐glucose (4) and ^18^F‐2‐deoxy‐2‐fluoro‐D‐mannose (8) by the direct fluorination of 3,4,6‐tri‐0‐acetyl‐D‐glucal with ^18^F‐F~2~ is described. ^14^C‐2‐deoxy‐2‐fluoro‐D‐glucose has been synthesized from ^14^C‐3,4,6‐tri‐0‐ace
