鱼饵制作摘要：The chitin obtained from crustacean shell waste and other renewable resources may be ud as a primary feedstock in the biorefineries of the future. Accordingly, the incorporation of chitin‐derived building blocks into new synthesis process will accentuate the utility of this biopolymer, particularly in 孕产期保健
the production of bio‐bad small molecules that contain one or more nitrogen atoms. Herein we report that enantioenriched 2‐amino sugars are readily accessible from the chitin‐derived platform 3‐acetamido‐5‐acetylfuran (3A5AF). Subjecting 3A5AF to a Noyori reduction–Achmatowicz rearrangement quence gave N‐acetyl‐l‐redno (RedNAc) in excellent yield and enantiopurity. Acetamide hydrolysis gave l‐redno, a rare 2‐amino sugar found in natural anthracycline and angucycline antibiotics. RedNAc
