A new photorearrangement of N-alkanoyl β-enaminones involving spiranic β-lactams as intermediates
摘要:
Under irradiation, N-alkanoyl, beta-enaminones are transformed into spiranic beta-lactams which give functionalized cycloalkenones in good yields, through an elimination reaction promoted by alumina.
spiranic β-lactams which undergo CN bond cleavage during chromatography on alumina giving cycloalkenones functionalized at position 3. This new rearrangement has been applied to the synthesis of α-amino-β,γ-unsaturated amides in one step and gives convenient yields.
