A new, one-pot, two-stage procedure for the preparation of the alpha- and beta-D-glucopyranosyl ureas has been developed. Oxidation of glucopyranosyl isocyanides provides glucopyranosyl isocyanates, which can be trapped in situ with amines to afford good yields of glucopyranosyl ureas. Application of this method establishes the successful synthesis of the hitherto unknown N,N'-di-alpha,alpha- and alpha
已经开发了一种新的,一锅,两阶段的制备α-和β-D-吡喃葡萄糖基脲的方法。吡喃葡萄糖基异氰酸酯的氧化提供了吡喃葡萄糖基异氰酸酯,其可以用胺原位捕获以提供良好产率的吡喃葡萄糖基脲。该方法的应用建立了迄今为止未知的N,N′-二-α,α-和α,β-D-吡喃葡萄糖基脲的成功合成。
