The stereoselective total synthesis of atpenins A4 (2) and B (3), harzianopyridone (4), and NBRI23477 B (5) have been developed using a convergent approach involving the coupling reaction of a common iodopyridine with an aldehyde corresponding to the appropriate side chain of the desired compound. Furthermore, the absolute configurations of atpenin B (3), harzianopyridone (4), and NBRI23477 B (5) have been unambiguously determined.
利用一种收敛方法,即普通碘吡啶与对应于所需化合物适当侧链的醛发生偶联反应,开发出了立体选择性全合成阿替匹灵 A4 (2) 和 B (3)、hazianopyridone (4) 以及 NBRI23477 B (5)。此外,还明确确定了阿替匹林 B (3)、哈嗪吡啶酮 (4) 和 NBRI23477 B (5) 的绝对构型。
