The group and face-selective cycloaddition of the enantiopure cyclopentadiene 4 to the tyrosine-related spirocylohexadienone 10 provided a high yield of the enantiomerically pure cyclohexadienone 11. Stereoselective transformations at the remaining double bond followed by a thermal retro-process, finally giving rise to the chromophore of the marine agelorin antibioticcs isolated from the sponge Agelas
对映体纯的环戊二烯4与酪氨酸相关的螺环己二烯酮10的基团和面选择性环加成反应提供了高纯度的对映体纯的环己二酮11。在剩余的双键处进行立体选择性转化,然后进行热逆过程,最终产生从海绵Agelas oroides Schmidt分离出的海洋苦瓜素抗生素的发色团。
