ChemInform Abstract: Synthesis of Azabicyclo(3.3.1)nonanes and Dibenzo(b,d)pyrans from 3-Aryl-2,4-dicarboethoxy-5-hydroxy-5-methylcyclohexanones as Potential Antimicrobial Agents.
Abstract
Double Mannich reaction of the cyclohexanones (I) with formaldehyde (II) and the amines (III) and subsequent treatment with oxalic acid (IV) yield the azabicyclononanes (V).
ChemInform Abstract
Double Mannich reaction of the cyclohexanones (I) with formaldehyde (II) and the amines (III) and subsequent treatment with oxalic acid (IV) yield the azabicyclononanes (V). Cyclocondensation of (I) with the phenols (VI) leads to the formation of the dibenzopyrans (VII).
