为发展含硫手性配体,以L-甲硫氨酸为手性源,经酯化、缩合、还原氨化等反应,设计合成了一种新的手性含硫二茂铁基β-氨基羧酸酯,其结构通过IR、1H NMR,^13CNMR、HRMS进行了表征.
A novel sulfur- containing ferrocenyl optically pure carboxylic acid ester has been successfully synthe- sized from readily available L- methionine through esterification, condensation, and reductive alkylation. The no- vel optically pure carboxylie acid ester was characterized by IR, 1H NMR, 13C NMR and HRMS.
