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.
