摘要

Michael addition of or-nitroketones to methyl vinyl ketone or acrylaldehyde followed by denitration with Bu3SnH affords 1,5-dicarbonyl compounds in good yields. ... 1,5-Dicarbonyl compounds (3) are an important class of com- pounds especially as intermediates for the preparation of cyc1ohexenones.l The available routes to (3) include 1,4- addition of enolates or enolate equivalents to or$-unsaturated carbonyl compounds,2 or alkylation of ketones with a 3-0x0- alkyl ...
