earlier described reaction of homophthalic anhydrides with aromatic ketones and ammonium acetate was tested for cyclic ketones (yielding spirocyclic motifs) and aliphatic aldehydes. In contrast to previous findings, the reaction was found to require no catalyst at all and to be applicable, in the non-catalyzed format, to these new carbonyl substrates as well as aromatic ketones. The reaction typically proceeds
Diastereoselective and one-pot synthesis of trans-isoquinolonic acids via three-component condensation of homophthalic anhydride, aldehydes, and ammonium acetate catalyzed by aspartic acid
Aspartic acid has been developed as a versatile and highly efficient organocatalyst for the three component combination of homophthalic anhydride, aldehydes, and ammonium acetate to afford trans-isoquinolonic acids. The reactions were carried out in acetonitrile under reflux conditions. Aspartic acid as an efficient organocatalyst exhibits dramatically improved diastereoselectivity compared with previously
