Daan J.A. Crommelin,Jon S. B. de Vliegerycles can be obtained by 1,3-dipolar cycloaddition reactions between an olefin and a nitrile oxide or a nitrone. This reaction generates one C–C and one C–O bond and up to three chiral centres in one step. In the present chapter, we aim to summarize and discuss reports of these cycloadditions on sug
