Abstract: We have developed a simple, metal‐free annulation of phosphole sulfides through intramolecular Alder‐ene reaction involving a 1,6‐enyne component. This atom‐efficient cyclization pathway provides phospholene fused polycycles with high yields and excellent regioselectivity. The 1,6‐enyne cyclization… read more here.

Abstract: An efficient and practical method for the preparation of the phospholene fused β-phosphinolactam skeleton from α-C2-bridged biphospholes and nitrones is described. The dissociation of biphospholes generates transient 1-phosphafulvenes, followed by oxidation with nitrones to give… read more here.
