Abstract

Addition of hydrogen cyanide to 9-methyl-Δ4-octalone-3 (IIb), as a model, yielded both cis- and trans-ketonitriles the configurations of which are assigned on the basis of IR spectra of the hydrolysed products. Similar addition of hydrogen cyanide to 9β-methyl-8β-hydroxy-Δ4-octalone-3 (IIc) gave the corresponding cis- and trans-hydroxy-keto-nitriles, configurations of which were proved by their conversion into cis- and trans-keto-nitriles obtained in the model study. In contrast to the model experiment where the trans-product predominated, the cis-isomer was the major product of addition to IIc.
