## Abstract The carbonβ13 n.m.r. spectra of several oxaziridines were measured. Aliphatic and aromatic __ipso__ carbon atoms __trans__ to the lone pair of nitrogen in oxaziridines were shifted upfield by __c.__ 9 ppm, and 3.4 ppm, respectively, in comparison with isomers of inverted configuration.
The "C NMR spectra of 21 catechin derivatives substituted at C-6/C-S by bromine and/or hydrogen and at oxygen by methyl, acetyl and/or hydrogen have been analysed in deuteriated acetone and chloroform. When a methoxy group is flanked by two bulky orrho substituents (6-Br and C4), the M e 0 and ortho
