In a simple and general protocol, the treatment of Mannich base hydrochlorides, derived from acyclic and cyclic ketones, with Lawesson'sreagent, leads to novel 4H-1,3,2-oxathiaphosphorine derivatives in good yields. A possible reaction mechanism, involving a [4+2] cycloaddition, is proposed. GRAPHICAL ABSTRACT
