divergent synthesis of 10 icetexane natural products based on a proposed biogenetic cationic ring expansion of a reduced carnosic acid derivative is described. Of these icetexanes, (+)‐salvicanol, (−)‐cyclocoulterone, (−)‐coulterone, (−)‐obtusinone D, and (−)‐obtusinone E have been synthesized for the first time. In addition, the hypothesis for the non‐enzymatic biogenesis of benzo[1,3]dioxole natural products
描述了基于还原的肌酸衍生物的拟议的生物遗传阳离子环扩链的10种冰烷天然产物的发散性合成。在这些冰tex烷中,首次合成了(+)-山杨醇,(-)-环香豆酮,(-)-香豆酮,(-)-奥布他酮D和(-)-奥布他酮E。另外,已经通过实验研究了苯并[1,3]二恶唑天然产物的非酶促生物发生假说。还提供了有关亚甲二氧基单元非生物形成的其他实验证据,因为醌(+)-komroviquinone的光解导致含[1,3]二恶唑的天然产物(-)-环库尔酮和(+)-的形成。科马罗匹螺酮。
