Abstract The synthesis of polycyclic aromatic compounds generally requires stoichiometric oxidants or homogeneous metal catalysts, however, the risk of contamination of inorganic residues can affect their properties. Here we present a microwave (MW)-

Multicomponent double Mannich alkylamination involving C(sp2)–H and benzylic C(sp3)–H bonds

Autor: Zhencheng Lai, Rongkai Wu, Jiaming Li, Xing Chen, Linwei Zeng, Xi Wang, Jingjing Guo, Zujin Zhao, Hironao Sajiki, Sunliang Cui

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-8 (2022)

The Mannich reaction is a three-component reaction for preparing alkylamines, but the nucleophilic components rely on C(sp2)−H and activated C(sp3)−H bonds. Here, the authors report an unprecedented multicomponent double Mannich alkylamination fo

Syntheses of 25-Adamantyl-25-alkyl-2-methylidene-1α,25-dihydroxyvitamin D3 Derivatives with Structure–Function Studies of Antagonistic and Agonistic Active Vitamin D Analogs

Autor: Kazuki Maekawa, Michiyasu Ishizawa, Takashi Ikawa, Hironao Sajiki, Taro Matsumoto, Hiroaki Tokiwa, Makoto Makishima, Sachiko Yamada

Publikováno v: Biomolecules, Vol 13, Iss 7, p 1082 (2023)

The active form of vitamin D3, 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3], is a major regulator of calcium homeostasis through activation of the vitamin D receptor (VDR). We have previously synthesized vitamin D derivatives with large adamantane (AD) r

Skeletal reorganization divergence of N-sulfonyl ynamides

Autor: Linwei Zeng, Yuxin Lin, Jiaming Li, Hironao Sajiki, Hujun Xie, Sunliang Cui

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-10 (2020)

Skeletal reorganizations are intriguing processes in chemical synthesis due to their mechanism, atom-economy and synthetic versatility. Herein, the authors describe a divergent skeletal reorganization of N-sulfonyl ynamides to thiete sulfones and pro
