D-Threonine-L-tert-leucine-derived bifunctional phosphine, Cat. 11, catalyzedhighlyenantioselective [3+2] annulation of maleimides with allenes has been disclosed, allowing the synthesis of optically active functionalized bicyclic cyclopentenes containing two tertiary stereogenic centers in good to high yields along with good to high enantioselectivities.
