Halogenated Pyridine Derivatives from Cycloaddition / Cycloreversion of Oxazinone and Haloalkyne Precursors
{{output}}
This study explores the merged cycloaddition/cycloreversion of 1,4-oxazinone substrates with haloalkyne 2π reaction components. Haloalkynes proved generally competent in the Diels-Alder operation and exerted a small influence on the regioselection of the reac... ...
