A Staudinger reaction between methoxyketene and two different imines formed from citral afforded, after chemical transformation, the (E/Z)-4-alkenylepoxy-2-azetidinones 2, 3 and 4. These compounds, by reaction with Cp2TiCl, did not cyclize to afford

The review covers work published in the calendar year 2015. The synthesis and reactivity of four-membered heteroatom-containing cycles are reviewed. New developments in the chemistry of these strained heterocycles, especially β-lactams, are covered.

During synthetic studies on anti-elastase polycyclic β-lactams from conveniently substituted monolactams, we attempted to obtain an N-(1 -methoxycarbonyalkylidene)-β-lactam by αselenoxide elimination. Although the desired alkenes 5 were obtained,
