Enyne monomers derived from D-xylose underwent living cascade polymerizations to prepare new polymers with a ring-opened sugar and degradable linkage incorporated into every repeat unit of the backbone. Polymerizations were well-controlled and had li

Achieving several desired transformations in a single operation remains one of the obvious goals in the synthetic organic chemistry. Herein we developed a multicomponent reaction for the preparation of alkenylated oxyindoles, bearing a quaternary alc

Monomers derived from glucose and galactose, which contain an endocyclic alkene (in the sugar ring) and a terminal alkyne, underwent a cascade polymerization to prepare new polymers with the ring-opened sugar incorporated into the polymer backbone. P

A one-pot, stereoselective construction of 2,3-dihydroxy-2,3-diaryltetrahydrofurans has been achieved via N-heterocyclic carbene (NHC)/base-mediated domino reactions of aldehydes and vinyl selenone. The products containing two contiguous quaternary h

The strained epoxide ring of oxirane-derived furanoside and pyranoside of d-fructose are regioselectively opened by various primary and secondary amines as well as azide to yield C4-alkylamino-C4-deoxy and the corresponding azido derivatives. The epo

D-Fructose, an inexpensive biomass precursor available on a large scale, has been used for the generation of enantiomerically pure chemical entities. Construction of vinyl selenone moieties on cyclic skeletons of d-fructose led to the highly reactive

Divinyl sulfones derived from pyranoside skeletons afforded 1,1-dioxothiomorpholine with predefined asymmetric environments. Although the exocyclic vinyl sulfone group easily reacts with primary amines, the intramolecular addition pattern of the seco
