Abstract
The nucleophile-induced rearrangement of cyclic N-alkoxy-N-(silyloxy)enamines was investigated. As a result, a new strategy for the synthesis of β-pyranone and β-furanone derivatives from nitro compounds is suggested.
Key words
nitroso acetals - rearrangement - nitrogen heterocycles - 1,2-oxazines - aliphatic nitro compounds
