Diisoproxide derivatives, generated in situ , of novel enantiopure dichloro Cu(II) and Zn(II) complexes supported by N 1 , N 1 ‐dimethyl‐ N 2 ‐[( 1R )‐myrtenylmethyl]ethane‐1,2‐diamine were assessed in ring opening polymerization of rac ‐LA, which displayed excellent activity and stereoselectivity. ( L )Cu(OCHMe 2 ) 2 resulted in complete conversion of monomer in 80 s and yielded PLA that gave preference for heterotactic enchainment with P r = 0.84 at 25 °C.
