number of aldehydes with Abrine methyl ester (1) was performed at room temperature to furnish mainly 3 and high ee was obtained in enantioselective of Et2Zn with PhCHO catalyzed by chiral 1,2,3,4-tetrahydro-β-carboline derivatives 5 synthesized from 3.
在室温下,许多醛与Abrine甲基酯(1)进行不对称的Pictet-Spengler反应,主要提供3,而在手性1,2,3,4-手性的PhCHO催化下,PhCHO对Et 2 Zn的对映选择性得到高ee。由3合成的四氢-β-咔啉衍生物5。
