Synthesis, structure and catalytic activity of organozinc complexes derived from chiral sulfonylamidoazetidines

A series of chiral organozinc complexes [(L1)ZnEt]2 (1), [(L2)ZnEt]2 (2) and [(L3)ZnEt]2 (3) have been prepared by ethane elimination reaction between ZnEt2 and the corresponding chiral sulfonylamidoazetidine ligands, (1′S,2S,3S)-1-(1′-Phenylethyl)-2-phenyl-3-isopropylsulfonamidoazetidine (HL1), (1′S,2S,3S)-1-(1′-Phenylethyl)-2-phenyl-3-(p-tolylsulfonamido)azetidine (HL2), and...
