Abstract
3-(pyrrolidin-2-ylmethylamino)naphthalen-2-ol(compoundⅠ) is a new organocatalyst which can effectively catalyze asymmetric Michael addition.The reactions proceeded in good to high yield and excellent enantioselectivities.It's generally considered that hydrogen bond is likely formed between the catalyst and the reactant β-nitrostyrene.In the interest of research this process,We synthesized the compound 1-(2-((3-hydroxynaphthalen-2-ylamino)methyl)pyrrolidin-1-yl)-2,2-dimethylpropan-1-one(compound Ⅱ).In this study,1D and 2D nuclear magnetic resonance(NMR) experiments were used for the assignments of 1H and 13C NMR signals of compound Ⅱ,which may be of help for further investigate the catalyzing mechanism.In addition,may supply reference for assignments of similar chemicals.
