Abstract Several N-(substituted phenyl) carbamoyloxylalkyl-1, 3-heterocycles of the structure 3 were prepared from their respective α-hydroxyalkyl-1, 3-heterocyclic alcohols 1. Efficient syntheses of the prerequisite novel 1, 3-heterocyclic alcohols, such as 2-(α-hydroxyalkyl)-2- oxazolines,− 5, 6-dihydro-1H-1, 3-oxazines,− 1, 4, 5, 6-tetra-hydropyrimidines,-imidazolines, and 4, 5, 6, 7-tetrahydro-1H-1, 3-diazepines were developed. Stannous octoate was found ...
