Determination of the configuration and conformation of some epoxybicycloalkanones using the epoxide ring current effect
Abstract
A ring current effect due to the oxiran ring has been used as an aid to structure elucidation of various novel epoxides derived from the 6-azabicyclo[3.2.0]hept-2-en-7-ones (1) and (4), the 2-oxabicyclo[3.3.0]oct-6-en-3-ones (7), (8), and (11), and the bicyclo[3.2.0]hept-2-en-6-one (14).
