In this articale, we have described a new practical cyclocondensation synthesis for a series of [1,2,4]triazolo[4,3-c]pyrido[3,2-e] pyrimidine and pyrido[2',3':4,5] pyrimido[6,1-c][1,2,4] triazine ...
New practical approaches to the synthesis of complex heterocycles are reviewed. Medicinal chemistry generally involves the preparation of a lead drug candidate on a milligram scale and uses ...
Organocatalysts consisting of organic compounds without metal elements are receiving much attention as next generation catalysts in the hope of reducing environmental burden and coping with exhaustion ...
