The natural product 6,7-dehydroartemisinic acid from Artemisia annua has been synthesized in four steps from artemisitene, which was in turn prepared in four steps from commercially available artemisinin. The forward synthesis involves the acid degradation of artemisitene and some comparisons are made between the products from this reaction and the more extensively studied acid degradation reaction of its 11,13-dihydro analogue, artemisinin.
从黄花蒿中提取的天然产物 6,7-脱氢青蒿酸是通过四个步骤从青蒿烯合成的,而青蒿烯又是通过四个步骤从市售青蒿素制备的。正向合成涉及青蒿烯的酸降解,并对这一反应的产物与其 11,13-二氢类似物青蒿素的酸降解反应进行了一些比较。
