Abstract

The'H NMR spectra were recorded on a Varian EM-390 spectrometer in dimeth~ 1-d~ sulfoxide with DSS as the internal standard. Exchangeable protons were detected by the addition of DzO. Melting points were determined on a Thomas-Hoover capillary melting point apparatus and are not corrected. Mass spectra were taken on a Varian 11243 spectrometer. F'ermethylations were carried out in dimethyl sulfoxide by using NaH and ...
