[4 + 2] Cyclization of para-Quinone Methide Derivatives with Alkynes

Autor: Guang-Jian Mei, Shao-Li Xu, Chen-Yu Bian, Feng Shi, Wen-Qin Zheng

Publikováno v: The Journal of Organic Chemistry. 83:1414-1421

The first cyclization of para-quinone methide derivatives with alkynes was established by utilizing the [4 + 2] reaction of ortho-hydroxyphenyl-substituted para-quinone methides with ynones or benzyne, which efficiently constructed the scaffolds of c

Catalytic Asymmetric Construction of the Tryptanthrin Skeleton via an Enantioselective Decarboxylative [4 + 2] Cyclization

Autor: Shao-Li Xu, Guo-Hao Li, Chen-Yu Bian, Guang-Jian Mei, Wen-Qin Zheng, Feng Shi

Publikováno v: Organic Letters. 19:3219-3222

The first catalytic asymmetric construction of the tryptanthrin skeleton has been established, taking advantage of a palladium(0)/chiral ligand-catalyzed enantioselective decarboxylative [4 + 2] cyclization of vinyl benzoxazinanones with isatins. Thi

Prolonged basaltic magmatism and short-lived magmatic sulfide mineralization in orogenic belts

Autor: Jun-Nian Yi, Lie-Meng Chen, Yufeng Deng, Song-Yue Yu, Wen-Qin Zheng, Qing-Lin Liang, Wei Xie, Xie-Yan Song, Bin Fu

Publikováno v: Lithos. :106114

Economically important Ni-Cu sulfide deposits occur in orogenic belts worldwide. However, the duration of timing and geological processes critical for generation of high-Mg basaltic magma and Ni-Cu sulfide mineralization during orogeny have not been

Apatite geochemistry of the Taihe layered intrusion, SW China: Implications for the magmatic differentiation and the origin of apatite-rich Fe-Ti oxide ores

Autor: Lie-Meng Chen, Song-Yue Yu, Yu-Wei She, Wen-Qin Zheng, Xie-Yan Song

Publikováno v: Ore Geology Reviews. 78:151-165

The Taihe intrusion is one of the layered intrusions situated in the central zone of the Emeishan Large Igneous Province (ELIP), SW China. The cyclic units in the Middle Zone of the intrusion are composed of apatite-magnetite clinopyroxenite at the b

The formation of P-rich Fe–Ti oxide ore layers in the Taihe layered intrusion, SW China: Implications for magma-plumbing system process

Autor: Yan Luan, Song-Yue Yu, Yu-Wei She, Wen-Qin Zheng, Lie-Meng Chen, Xie-Yan Song

Publikováno v: Ore Geology Reviews. 57:539-559

The Taihe intrusion is one of the layered intrusions that host giant Fe–Ti oxide deposit in the central part of the Emeishan Large Igneous Province, SW China. Different from the other layered intrusions, the Taihe intrusion has a massive Fe–Ti ox
