A formal total synthesis of the antitubercular natural product was accomplished. This work was undertaken to address certain stereochemical problems in our initial synthesis. By using an ester group as a surrogate for a methyl group, we were able to intercept a key intermediate in our first synthesis with better selectivity and greater convergence than had previously been the case.
完成了抗结核天然产物的正式全合成。进行这项工作是为了解决我们最初合成中的某些立体化学问题。通过使用酯基团作为甲基基团的替代物,我们能够在我们的第一次合成中截获一个关键中间体,并且比以前的情况具有更好的选择性和更大的收敛性。
