在前面的论文中,我们报道了光学纯烯酮1的合成,它是五环三萜的一般收敛合成中A环和B环的潜在有用的合成子。2.本文报道了烯丙基溴2的合成,它是一种合成反香树脂D环和E环的合成子。
In the preceding paper, we reported the synthesis of optically pure enone 1, a potentially useful synthon for rings A and B in a general convergent synthesis of pentacyclic triterpenes. 2 In this paper, we report the synthesis of allylic bromide 2, a synthon for rings D and E of ß-amyrm.
