Abstract

An organocatalytic ‘one-pot’ synthesis of highly functionalized 3,4,5,6-tetrasubstituted dihydropyrans has been developed. Excellent enantio- and diastereo selectivity with good yields are some of the salient features of this methodology. This reaction takes advantage of proline based catalysts and follows stepwise sequential transformations including Knoevenagel condensation–Michael addition–hemiacetalization towards the synthesis of complex dihydropyranol framework.
