A detailed study directed toward the development of a versatile synthetic route to the interesting dimeric natural product yuehchukene (1) and its epimer, 6a-epi-yuehchukene (2), has been completed. Due to the anti-implantation activity associated with 1, it was important to provide a synthetic strategy not only to 1, but to a family of yuehchukene analogues that, hopefully, would reveal superior chemical stability and (or) elevated biological activity. The experiments described herein and which utilize the readily available and inexpensive isophorone (6) satisfy these requirements. Key words: yuehchukene synthesis, yuehchukene analogues, anti-implantation activity.
一项详细研究已完成,旨在开发一种通用的合成途径,以合成有趣的二聚天然产物月竹烯(1)及其对映体6a-epi-月竹烯(2)。由于与1相关的抗着床活性,因此提供一种合成策略不仅对1,而且对一系列月竹烯类似物是重要的,希望这些类似物能具有更好的化学稳定性和(或)更高的生物活性。本文所述的实验利用了易得且廉价的异戊酮(6),满足了这些要求。关键词:月竹烯合成,月竹烯类似物,抗着床活性。
