Anomeric pairs of L-arabinofuranosides of various aliphatic alcohols were synthesized and then investigated by n.m.r. spectroscopy. The "C-n.m.r. glycosylation shift of these L-arabinofuranosides is very similar to that of L-arabinopyranosides and other glycopyranosides reported previously. The 3JH.
## Abstract The ^1^H‐ and ^13^C‐NMR spectra of __N__‐acetyl‐L‐alanine methylester and __N__‐acetyl‐L‐alanine methylamide were measured to examine the modes of self‐association of these molecules in solution. The different dilution shifts between these molecules seem to correspond to the difference
## Abstract We have developed a stereospecific chemomicrobiological synthesis of labeled tryptophan. L‐[3‐^13^C]Serine, [1‐^15^N]‐ and [2‐^13^C]indole were used as precursors for the synthesis of L‐[β‐^13^C]‐, L‐[1′‐^15^N]‐, and L‐[2′‐^13^C]tryptophan, respectively. The labeled precursors were inco
