Abstract
A heterogeneous catalyst of natural quinine supported on the mesoporous SBA15 of short mesochannels was originally synthesized through a simple cocondensation approach for asymmetric organocatalysed Michael addition of malononitrile to chalcones The catalytic activity was greatly enhanced compared with the conventional analogue Furthermore the enantioselectivity could also be significantly improved for all substratesThe authors are grateful to the National Natural Science Foundation of China 20773069 the Specialized Research Fund for the Doctoral Program of Higher Education 200800551017 and 20100031120029 the Fundamental Research Funds for the Central Universities and MOE IRT0927 for financial support
