Asymmetric syntheses of (R)-2-aryl- and (R,R)-2,5-bis(aryl)pyrrolidines were described starting from chiral aromatic imines derived from (R)-phenylglycinol, in which the diastereoselective additions of Grignard reagents to the chiral imines and 1,3-oxazolidines were used as the key reaction step.
(R)-2-芳基-和(R,R)-2,5-双(芳基)吡咯烷的不对称合成是从衍生自(R)-苯基甘氨醇的手性芳族亚胺开始描述的,其中非对映选择性地添加了格氏试剂手性亚胺和1,3-恶唑烷的反应用作关键反应步骤。
