Abstract: Chiral heterocycles are widely occurring in many compounds of interest, but their efficient synthesis is challenging. We present here the enantioselective and diastereoselective synthesis of densely substituted chiral pyran derivatives. Diastereodivergency of the oxa-Diels-Alder reaction… read more here.

Abstract: Michael, Michael-annulation, and oxa-Diels-Alder reactions of carbohydrate derivatives that afford polyoxy-functionalized piperidine derivatives bearing tetrasubstituted carbon at the 3-position of the piperidine ring are reported. Iminium ions generated from carbohydrate derivatives with amines were converted… read more here.
