The concise and efficient synthesis of (+)-goniothalesdiol A and (–)-parvistone E (leiocarpin A), as well as the first total syntheses of (–)-6-epi-goniothalesdiol A and (–)-8-epi-9-deoxygoniopypyrone acetate, have been achieved in four or five longest linear steps based on the chiron approach. The potential biological activities of four 2,6-disubstituted tetrahydropyran-containing natural products
(+)-goniothalesdiol A 和 (–)-parvistone E (leiocarpin A) 的简洁高效合成,以及 (–)-6- epi -goniothalesdiol A 和 (–)-8- epi 的首次全合成-9-脱氧吡咯酮乙酸酯,基于 chiron 方法,已在四或五个最长的线性步骤中实现。基于一组人类癌细胞系、BV-2 小胶质细胞和 3T3-L1 前脂肪细胞,探索了四种含 2,6-二取代四氢吡喃的天然产物的潜在生物活性。我们的结果表明,这四种天然产物在 3T3-L1 前脂肪细胞中表现出显着的脂肪形成活性,但对癌细胞增殖或 LPS 刺激的小胶质细胞活化没有明显影响。
