Dialkyl acetals containing other functional groups can participate in stereoselective coupling reactions with chiral titanium enolates. Such an approach provides the protected γ-amino acid present in bistramides and FR252921 in a highly efficient manner.
含有其他功能团的二烷基乙缩醛可以与手性钛烯醇盐参与立体选择性耦合反应。这种方法高效地提供了在双三肽和FR252921中存在的保护γ-氨基酸。
