Studies on the addition of nitrile oxides to 1-phenylthiobuta-1,3-diene, a new directed aldol condensation
Abstract
Addition of nitrile oxides to 1-phenylthiobuta-1,3-diene is regiospecific, allowing preparation of the hitherto unknown amino phenylthioallylic alcohols (3) and hence the unsaturated aldehydes (4).
