A facile and expeditious entry to acyclic carbohydrate-derived 1,2-diazabutadienes
摘要:
Chiral 1,2-diaza-1,3-butadienes derived from acyclic monosaccharides are easily prepared from the corresponding and readily available unprotected sugars in a two-step sequence.

Incorporation of the photolabile azo group into an unsaturated sugar chain affords a class of glycomimetics susceptible of thermal and photo‐induced switches under mild conditions (sunlight irradiation). Herein, such stereomutations and mechanistic routes are disentangled by experiment and DFT calculations.
