Abstract
A green and facile synthesis of 1-(α-aminoalkyl)-2-naphthols, generally called Betti bases (BB) in the presence of Baker’s yeast (BY), acts as an efficient catalyst, and ethanol as a green solvent. In this methodology, the BY is used first time as a biocatalyst (enzyme). This protocol has some inherent advantages, such as mild reaction conditions, no environmental pollution, simple work up, no need of column chromatography, diversity of reactant and desired 1-(α-aminoalkyl)-2-naphthols (Betti bases) (4a-r) are obtained in good-to-excellent yields. This is the first report on Baker’s yeast-catalyzed (BYC) synthesis for BB. This present bio-catalytical route for synthesizing BB in the presence of biocatalysts like BY is anticipated to open a gateway to synthesized complexed biological active molecules counting BB.
