Α-oximono-esters as precursors to heterocycles – generation of oxazinone n-oxides and cycloaddition to alkene dipolarophiles
(Royal Society of Chemistry (RSC), 2003-01-01)Preparation of a series of terminally and internally substituted delta-alkenyl and delta-alkynyl esters 6,7 and 9, potential precursors to oxazin-2-one nitrones, has been attempted. Condensation between pyruvic or benzoylformic ...
