A highly efficient approach to vanillin starting from 4-cresol
TL;DR: In this article, a highly efficient approach to the famous flavor and fragrance compound vanillin has been developed starting from 4-cresol with the attention focused on improving the sustainability of all the reactions.
Journal ArticleDOI
Cu(OAc)2-catalyzed remote benzylic C(sp3)–H oxyfunctionalization for CO formation directed by the hindered para-hydroxyl group with ambient air as the terminal oxidant under ligand- and additive-free conditions
TL;DR: A hindered para-hydroxyl group-directed remote benzylic C(sp3)-H oxyfunctionalization has been developed for the straightforward transformation of 2,6-disubstituted 4-cresols, 4-alkylphenols and 4-hydroxybenzyl alcohols into various aromatic carbonyl compounds as discussed by the authors.
Journal ArticleDOI
Concurrent synthesis of vanillin and isovanillin
TL;DR: In this paper, a method for concurrent synthesis of vanillin and isovanillin was developed by a nonregioselective Vilsmeier-Haack reaction of O-alkyl guaiacols.
Journal ArticleDOI
Alternate Synthesis of Apixaban (BMS-562247), an Inhibitor of Blood Coagulation Factor Xa
Jian-An Jiang,Ya-Fei Ji +1 more
TL;DR: In this article, an alternative approach to apixaban was described, which features a novel and cost-effective synthetic strategy to construct a key N-phenylvalerolactam intermediate 4 from 4-nitroaniline.
Journal ArticleDOI
Tandem C-C/C-N Formation via Palladium-Catalyzed C-H Activation/Styrenation and Sequential Annulation of O-Methylketoxime with Styrenes.
TL;DR: A novel route for tandem C-C/C-N formation via palladium-catalyzed C-H activation/styrenation and annulation of O-methylketoxime with styrenes to synthesize benzothienopyridine and benzofuropyridines has been developed.
