we show the limitations of this approach when quaternary C centres at N-1 became a key target for the programme. To access this key substructure, we developed an efficient multi-component reaction (MCR) from readily available α-amino acid precursors.
的制备Ñ -1选择性烷基化尿嘧啶中间体通常要求选择性保护Ñ -3随后烷基化以Ñ -1和随后除去保护基团。在这封信中,我们展示了当N -1的四级C中心成为该计划的主要目标时这种方法的局限性。为了访问此关键子结构,我们从容易获得的α-氨基酸前体中开发了有效的多组分反应(MCR)。
