Preparation and properties of some phytotoxic 2-benzyloxy-8-oxabicyclo[3.2.1]octane derivatives
Abstract
The preparation and biological activity of a novel group of herbicides is described. These 2-benzyloxy-8-oxabicyclo[3.2.1]octanes are readily obtained from the cycloadducts formed between various olefins and 3-oxidopyrylium ylides, prepared from 6-acetoxypyran-3(6H)-ones.
