2-Aryl-4-quinolone Synthesis Using the Thermal Rearrangement of Iminocyclobutenones
摘要:
2-Aryl-4-quinolone synthesis is developed using the thermal rearrangement of iminocyclobutenones formed by a conjugate addition reaction of ketene silyl acetals to alkynyl imines.
In the present study, the stereodivergent synthesis of both cis- and trans-β-lactams is presented using the following three reactions: iminocyclobutenone formation, chemoselective reduction of imino groups, and thermalrearrangement of aminocyclobutenones as crucial steps, in which the starting materials, iminocyclobutenones, were readily synthesized using conjugate addition reactions of alkynyl imines
