corresponding 4-hydroxy-6-substituted-9-oxa-1-azatricyclo[6.2.1.05,11]undec-5-ene-7,10-diones. On the basis of this newly developed Pauson−Khand reaction of 2-oxazolone-alkyne derivatives, the first total synthesis of (±)-8α-hydroxystreptazolone was accomplished in a highly stereoselective manner. In addition, (±)-7-epi-8α-hydroxystreptazolone was also synthesized.
2-恶唑酮衍生物与合适的庚炔基分子的分子内Pauson-Khand反应仅产生相应的4-羟基-6-取代的-9-oxa-1-氮杂三环[6.2.1.0 5,11 ] undec -5-ene-7 ,10-二酮。基于这种新开发的2-恶唑酮-炔烃衍生物的Pauson-Khand反应,以高度立体选择性的方式完成了(±)-8α-羟基链霉唑酮的首次全合成。另外,还合成了(±)-7 - epi -8α-羟基链霉唑酮。
