Metal- and base-free synthesis of imidazo[1,2-a]pyridines through elemental sulfur-initiated oxidative annulation of 2-aminopyridines and aldehydes

Org. Biomol. Chem., 2018, Accepted ManuscriptDOI: 10.1039/C8OB00981C, CommunicationJing Tan, Penghui Ni, Huawen Huang, Guo-Jun DengThe elemental sulfur-promoted oxidative cyclization reaction for the efficient synthesis of substituted imidazo[1,2-a]pyridines has been developed. Easily available 2-aminopyridines and aldehydes were directly assembled in highly atom-economic fashion through oxidative...The content of this RSS Feed (c) The Royal Society of Chemistry
