We describe a new route to access important pharmaceutical intermediates for the synthesis of constrained fused pyrazinones. These compounds are prepared in five to seven steps with a good overall yield from glycine methyl ester and commercial propanediol derivatives involving an intramolecular alkylation of a glycine moiety as key step.
我们描述了一种获得重要医药中间体以合成受限稠合吡嗪酮的新途径。这些化合物由甘氨酸甲酯和商业丙二醇衍生物分五到七步制备,总收率良好,其中涉及甘氨酸部分的分子内烷基化作为关键步骤。
