The first total synthesis of the mastigophorenes C (2) and D (3), natural ‘dimeric’ sesquiterpenes isolated from the liverwort Mastigophora diclados with interesting biological activities, is described. As previously for mastigophorenes A (1) and B, the divergent synthetic approach was first optimized on a simplified model system with a tert-butyl group instead of the chiral cyclopentyl residue, also
第一个全合成的马鞭草C(2)和D(3),天然的'二聚体'倍半萜烯,从有趣的生物学活性,从地榆中分离得到了马齿tig Mastigophora diclados。像以前对于扁桃体A(1)和B一样,首先在具有叔丁基而不是手性环戊基残基的简化模型系统上优化了发散性合成方法,还为了找到更容易获得的具有相似或什至改进的化合物生物活性。
