A protocol for the asymmetric trimethylenemethane (TMM) [3 + 2] cycloaddition reaction of alkynyl-substituted TMM donors and unsaturated N-acyl pyrroles employing a chiral bisdiamidophosphite ligand has been developed. This process generates alkynyl-substituted cyclopentanes in high yields and diastereo- and enantioselectivities. These chiral precursors are employed for the atom economic assembly of fused polycyclic hydrocarbons with hydroindene, hydroazulene, and hydrocyclopentanaphthalene scaffolds by consecutive cycloaddition reactions.
