A method for preparing an alkenylamine, or a salt, solvate or hydrate thereof, is disclosed. The method comprises reacting a alogen-substituted cyclic acetal or a derivative thereof under particular conditions to provide the alkenylamine, which may be optionally converted into a salt, solvate or hydrate thereof. A method for preparing a cyclic carbamate or cyclic dithiocarbamate, or a salt, solvate or hydrate thereof, is also disclosed. The method comprises reacting an alkenylamine under particular conditions to provide the cyclic carbamate or cyclic dithiocarbamate, which may be optionally converted into a salt, solvate or hydrate thereof. A method for preparing a 1,2-aminoalcohol or 1,2-aminothiol, or a salt, solvate or hydrate thereof, is also disclosed. The method comprises forming a cyclic carbamate or cyclic dithiocarbamate from an alkenylamine, and deprotecting the cyclic carbamate or cyclic dithiocarbamate to provide the 1,2-aminoalcohol or 1,2-aminothiol, which may optionally be converted into a salt, solvate or hydrate thereof.
揭示了一种制备烯基胺或其盐、溶剂合物或水合物的方法。该方法包括在特定条件下反应氯代取代的环缩醛或其衍生物以提供烯基胺,该烯基胺可以选择性地转化为其盐、溶剂合物或水合物。还揭示了一种制备环氨基甲酸酯或环二硫代氨基甲酸酯或其盐、溶剂合物或水合物的方法。该方法包括在特定条件下反应烯基胺以提供环氨基甲酸酯或环二硫代氨基甲酸酯,该化合物可以选择性地转化为其盐、溶剂合物或水合物。还揭示了一种制备1,2-氨基醇或1,2-氨基硫醇或其盐、溶剂合物或水合物的方法。该方法包括从烯基胺中形成环氨基甲酸酯或环二硫代氨基甲酸酯,并去保护环氨基甲酸酯或环二硫代氨基甲酸酯以提供1,2-氨基醇或1,2-氨基硫醇,该化合物可以选择性地转化为其盐、溶剂合物或水合物。
