A stereorational total synthesis of the structurally (−)-enantiomer of the unique guanidine containing natural product ptilocaulin is described. This efficient synthesis (14 steps, 7.4% overall yield) utilizes an intramolecular 1,3-dipolar cycloaddition as a key step and establishes that the natural product is the most stable of a number of possible isomers. This work also establishes the absolute
描述了独特的含有胍的天然产物枯草杆菌蛋白酶的结构(-)-对映异构体的立体全合成。这种高效的合成方法(14个步骤,总收率7.4%)利用分子内1,3-偶极环加成作为关键步骤,并确定了天然产物是多种可能异构体中最稳定的。这项工作还建立了枯草杆菌蛋白酶的绝对立体化学,如式3所示。
