✦ Synopsis

2D-N.m.r. (COSY) spectra of tetrasaccharides derived from the bacterial polysaccharides K54, produced by Klebsiella aerogenes serotype K54, and XM6 (from Enterobacter NCIB 11870) have enabled full assignment of the 'H-n.m.r. spectra. The 2D spectra, together with n.0.e. experiments, indicate that the Oacetyl group of K54 is located at O-2 of the L-fucose residue. The 13C-n.m.r. spectra of the polysaccharides have been assigned with the help of 2D-13C/'H shift-correlation methods.

Although many stereochemical features of vitamin D and its ieomeric precursor6 may be coneidered rather well established (1,2) by now, there remain a few intriguing questions. One of the problems that asked for further study, is concerned with the conformational analysis of tachyeterol (Fig. I). The
