Stereopopulation control. VII. Rate enhancement in the lactonization of 3-(o-hydroxyphenyl)propionic acids: dependence on the size of aromatic ring substituents
A systematic study of the reaction of a series of monosubstituted phenols 3 and 3-methylbut-2-enoic acid 4 in phosphorusoxychloride/zinc chloride revealed that the formation of 4-chromanones was strongly infuenced by the substituents and their position on the aromatic ring of the starting phenols.
