Ping, Yuan-Ji; Zhou, Yi-Ming; Wu, Liang-Liang; Li, Zong-Rui; Gu, Xin; Wan, Xiao-Long; Xu, Zhen-Jiang; Che, Chi-Ming published an article in 2021, the title of the article was Fe-BPsalan complex catalyzed highly enantioselective Diels-Alder reaction of alkylidene β-ketoesters.Synthetic Route of 10472-24-9 And the article contains the following content:
A practical, highly efficient iron-catalyzed asym. Diels-Alder reaction of various alkylidene β-ketoesters with dienes was developed. Both cyclic and acyclic alkylidene β-ketoesters underwent the reaction well with the Fe-BPsalan complex as the catalyst to afford the addition products including estrone analogs in excellent yields, good to high diastereoselectivities and excellent enantioselectivities under mild reaction conditions. DFT calculations revealed the critical role of the steric effect in directing the reaction selectivity. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Synthetic Route of 10472-24-9
