An asymmetric catalytic strategy in photocatalysis utilizing a chirality-induced approach through an organocatalytic/photoredox relay catalysis strategy is successfully achieved for the rapid construction of polycyclic compounds containing vicinal amino alcohols in a one-pot protocol. This methodology facilitates the efficient synthesis of diverse substituted polycyclic tetrahydroquinoline and benzofuran-derived vicinal amino alcohols, each containing five consecutive chiral centers, with high yields,excellent diastereoselectivities and enantioselectivities(up to 95% yield, >20:1 dr and 98% ee), under mild reaction conditions driven by sequential bifunctional squaramide organocatalyst-catalyzed [4+2] annulation and photocatalyst-catalyzed ketyl radical addition cyclization reaction process. Furthermore, investigations into the stereoselectivity mechanism and high-resolution mass spectrometry(HRMS) experiments on free radical trapping have provided evidence for elucidating the detailed mechanism of chirality-induced processes and chiral intermediate conversions in this procedure.

大气CO_(2)浓度升高等全球变化过程不仅能促进外来植物入侵,也能改变土壤丛枝菌根真菌(AMF)的群落结构,但我们并不清楚大气CO_(2)浓度升高促进外来植物入侵是否与其对外来入侵植物和本地植物AMF共生的影响有关。为回答这一问题,我们在环境和倍增CO_(2)浓度下连续3年栽培一年生外来入侵植物瘤突苍耳(Xanthium strumarium)与两种共存的一年生本地近缘植物,比较了AMF侵染率、土壤养分和土壤AMF群落组成的差异。研究结果表明,大气CO_(2)浓度升高只在少数情况下提高根系AMF侵染率,并且瘤突苍耳AMF侵染率的提高并不比本地种多。在环境CO_(2)浓度下,栽培第一年瘤突苍耳的AMF侵染侵染率显著高于两种本地植物;而栽培第二年和第三年与两种本地植物的差异不显著,因为两种本地植物的AMF侵染率随种植时间的增加而增加,而瘤突苍耳AMF侵染率受种植时间的影响较小。物种、CO_(2)浓度和种植时间对AMF侵染率的影响与它们对土壤养分和AMF群落的影响有关,土壤养分对AMF侵染率的影响可能比AMF群落组成的影响更大,因为后者也受土壤养分的影响。上述结果表明,与本地植物相比,入侵植物能更快地与AMF形成共生关系,有利于其适应和入侵新生境;在探究全球变化如大气CO_(2)浓度升高等对外来植物入侵的影响时,需要考虑AMF的影响和时间效应。
