Abstract
L-threonine (2S,3S) was obtained from easily available L-threonine (2S,3R) after four steps,then seven chiral ligands 9a-9g were prepared by the esterification,condensation,reductive alkylation,cyclization,then reduction with treatment with RMgX.All seven kinds of novel compounds were characterized by 1HNMR,13CNMR,IR and HRMS.Compound 9a was further characterized by X-ray diffraction.The X-ray structure analysis revealed that an intermolecular hydrogen bond is present.
