权利人:WATKINS EDMOND BLAKE; UREDI DILIPKUMAR; MOTATI DAMODER REDDY; UNION UNIV
摘要:The present invention relates to novel methods of preparation of substituted pyridines and the compounds produced therefrom. In particular, the present invention provides efficient methods for the construction of diversely substituted pyridines, with varying substitution patterns under simple and metal-free conditions with high atom- and pot-economy and excellent functional group tolerance, and which are useful for the synthesis of natural products.
