摘要: The monophenylation ofcis-1,2-cyclopentanediol with triphenylbismuth diacetate in the presence of chiral Cu(II) complexes as catalysts gavecis-2-hydroxy-1-phenoxy-cyclopentane enantiomeric excesses up to 38%. optically active ligands used were triamine derivatives 2,6-bis(aminomethyl)pyridine and diamine 2-(aminomethyl)pyridine. Selectivity occurred only latter auxiliary ligands.
