Abstract
It has been established on the basis of the results of 1H and 13C NMR, UV, and IR spectroscopy that 3-acyl-2-methylindole oximes each exist in the form of a mixture of two isomers with a predominance of syn-s-trans form. The proportion of the anti form rises (to 25–35%) with an increase in the volume of the alkyl radical in the oxime grouping.
