2-alkoxy- or acyloxy-2-aryl-1,3-propanediol or dioxane derivative, and process for its production

摘要

A compound that can be converted, at a low cost and in a simple way, into 2-aryl-1,3-propanediols serving as precursors for synthesizing felbamate acting as an antiepileptic has a structure represented by Formula (1): <IMAGE> (1) wherein Ar represents an aryl group; R1 represents a hydrogen atom or is R4 or R5, where R4 represents an alkoxy group having 1 to 10 carbon atoms and R5 represents a hydroxy group or an acyloxy group having 1 to 10 carbon atoms; and R2 and R3 are hydrogen atoms at the same time or R2 and R3 together form a group represented by Formula (2): <IMAGE> (2) wherein R6 and R7 each independently represent a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, or R6 and R7 together form an oligomethylene group having 2 to 10 carbon atoms.
