A series of optically enriched monofluorinated dipeptides incorporating an α-fluoro-α-amino acid were prepared by enantio- and diastereoselective electrophilic fluorination. This previously unsuccessful approach to fluorinated dipeptides can now be achieved with up to 73:27 enantiomeric ratio and high >98:2 diastereomeric ratio.
通过对映和非对映选择性亲电氟化制备了一系列掺有α-氟-α-氨基酸的光学富集的单氟化二肽。现在可以以高达73:27的对映体比例和高的> 98:2非对映体比例来实现这种以前不成功的氟化二肽方法。
