Asymmetric Organocatalytic Double 1,6-Addition: Rapid Access to Chiral Chromans with Molecular Complexity

Org. Chem. Front., 2020, Accepted Manuscript
DOI: 10.1039/D0QO00354A, Research Article
Indranil Chatterjee, Sourav Roy, Suman Pradhan, Krishan Kumar
An organocatalytic cascade vinylogous double 1,6-addition strategy for the synthesis of chiral chroman derivatives is reported. The cascade reaction follows oxa-Michael/1,6-addition reactions between ortho-hydroxyphenyl-substituted para-quinone methadies and 2,4-dienal derivatives to...

Ag2O-catalysed nucleophilic isocyanation: selective formation of less-stable benzylic isonitriles

Org. Chem. Front., 2020, Advance Article
DOI: 10.1039/D0QO00336K, Research Article
Taiga Yurino, Yuji Tange, Ryutaro Tani, Takeshi Ohkuma
Both primary and secondary benzylic isonitriles were exclusively produced by the Ag2O-catalysed reaction of benzylic phosphates and trimethylsilyl cyanide without formation of the thermodynamically favoured regioisomers, benzylic nitriles.

An Aspidosperma-type alkaloid dimer from Tabernaemontana bovina as a candidate for the inhibition of microglial activation

Org. Chem. Front., 2020, Advance Article
DOI: 10.1039/D0QO00296H, Research Article
Yang Yu, Si-Meng Zhao, Mei-Fen Bao, Xiang-Hai Cai
As a representative of twelve undescribed Aspidosperma-type alkaloid dimers, tabernaemontine F (6) inhibited microglial activation by blocking P38 MAPK activation, revealing a potential candidate for chronic neurodegenerative diseases.
