An expedient, solvent-free, mild base catalyzed intermolecular cyclization reaction has been developed to enable the one-pot synthesis of fourteen examples of cyclobutane-fused oxazolidine-2-thiones in good to high yields. Bicyclic structures of this type have not previously been described in the literature; they have a cis ring junction with both rings deviating slightly from planarity.

Abstract
An expedient, solvent-free, mild base catalyzed intermolecular cyclization reaction has been developed to enable the one-pot synthesis of fourteen examples of cyclobutane-fused oxazolidine-2-thiones in good to high yields. Bicyclic structures of this type have not previously been described in the literature; they have a cis ring junction with both rings deviating slightly from planarity.
