1,4-Dialkoxy 1,3-dienes and bis(dienes)–stereocontrolled synthesis and reactivity
摘要:
gamma-Aryloxy and -alkoxy alpha,beta-unsaturated dimethyl acetals are direct precursors to (1Z, 3E)-1,4-dialkoxy 1,3-dienes and bis(dienes) which are fine partners in cycloaddition reactions with classical dienophiles.

operationally simple and practical protocol to access N-CF2H amides and related carbonyl derivatives was developed. The protocol utilizes a one-pot conversion of thioformamides via desulfurization-fluorination and acylation, providing N-difluoromethylcarbamoyl fluoride that can be further diversified to a diversity of N-CF2H carbonyl compounds including amides, carbamates, ureas, thiocarbamates, and selenocarbamates
开发了一种操作简单且实用的获取N -CF 2 H 酰胺和相关羰基衍生物的方案。该方案利用硫代甲酰胺通过脱硫氟化和酰化的一锅转化,提供N-二氟甲基氨基甲酰氟,该氟化物可以进一步多样化为多种N -CF 2 H羰基化合物,包括酰胺、氨基甲酸酯、脲、硫代氨基甲酸酯和硒代氨基甲酸酯。丰富的功能。
