Interplay of metalloligand and organic ligand to tune micropores within isostructural mixed-metal organic frameworks (M'MOFs) for their highly selective separation of chiral and achiral small molecules

Autor: Qunsheng Guo, Rajamani Krishna, Madhab C. Das, Yabing He, Banglin Chen, Zhangjing Zhang, Shengchang Xiang, Cong Gui Zhao, Kunlun Hong, K. Mark Thomas, Jaheon Kim

Publikováno v: Journal of the American Chemical Society, 134(20), 8703-8710. American Chemical Society

Four porous isostructural mixed-metal-organic frameworks (M'MOFs) have been synthesized and structurally characterized. The pores within these M'MOFs are systematically tuned by the interplay of both the metalloligands and organic ligands which have

Organocatalyzed enantioselective synthesis of 2-amino-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carboxylates

Autor: Cong Gui Zhao, Naresh Ramireddy, Santhi Abbaraju

Publikováno v: Tetrahedron Letters. 52:6792-6795

The organocatalyzed enantioselective synthesis of biologically active 2-amino-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carboxylate derivatives was achieved using bifunctional cinchona alkaloids as the catalysts. Using quinine thiourea as the catalyst,
