标 题 :Process for Synthesis of Lactams
发明人：TAVARES FRANCIS XAVIER
权利人:TAVARES FRANCIS XAVIER
摘要:Methods for the synthesis of lactams are presented whereby a carboxylic acid of the formula HOOC—OR—NH-LG, wherein OR is an organic moiety and LG is a leaving group, is reacted with an acid, such as an organic acid, in particular a strong acid, and a dehydrating agent, which may be one in the same such as a strong acid anhydride, such that the amount of acid added allows for the desired transformation to take place without the loss of the leaving group (LG) before the cyclization, and recovering the lactam such as that of the formula (a), provided herein, wherein G represents the atom(s) needed to form a closed ring.

摘要:Substituted 1-hydroxy-2-(1,1-difluoroalkyl)-1H-imidazo-(4,5-b)pyridine compounds useful as herbicides; and intermediates useful in the synthesis of these compounds. In addition to exhibiting herbicidal activity, the substituted 1-hydroxy-2-(1,1-difluoroalkyl)-1H-imidazo(4,5-b)pyridine compounds are of low mammalian toxicity.
