• Novel types of compounds, <I>N</I>-tributylstannyl-2-oxazolidinone (<B>4a</B>) and tetrahydro-2<I>H</I>-1,3-oxazin-2-one (<B>4b</B>), are formed from the adduct of (<I>n</I>-Bu<SUB>3</SUB>Sn)<SUB>2</SUB>O (<B>1</B>) with ω-haloalkyl isocyanate (<B>2</B>), and the subsequent coupling reaction with alkyl halides gives a variety of <I>N</I>-substituted 2-oxazolidinones and tetrahydro-2-oxazinones in a one-pot procedure. Both the cyclization and the coupling reaction proceed quantitatively in the presence of HMPA which enhances the reactivity of the Sn–heteroatom bond by coordination.
