Full details of the total syntheses of slagenins A-C (1a-c) and their antipodes (2a-c), novel bromopyrrole alkaloids with a unique tetrahydrofuro[2,3-d]imidazolidin-2-one moiety, are described in which their absolute stereochemistry was established. The key step in the syntheses involves the efficient condensation of dihydrofuran-3-one or glyoxal with urea to construct the slagenin bicycle core.
slagenins AC(1a-c)及其对映体(2a-c),具有独特的四氢呋喃[2,3-d]咪唑啉二-2-酮部分的新型溴吡咯生物碱的总合成的全部详细信息,在其中进行了描述。建立了立体化学。合成中的关键步骤涉及二氢呋喃-3-酮或乙二醛与尿素的有效缩合,以构建slagenin自行车核心。
