tained from 3-methylisothia~ ole,~ via the hydrolysis of: 3-dibromometllylisothiazole.~ Reaction of the aldehyde with SH, OH in neutral aq solution gave isot hiazole-3- carboxaldoxime (la), configurationally pure according to its rimr spectrum. Since the original oxime was recovered in SOY0 yield from the alkaline hydrolysis of benzoylated la, the E configurationfi could be assigned'to la. This assignment was confirmed by the presence of ...
