Microwave‐Assisted Synthesis of Quinoline Derivatives from Isatin
摘要:
Microwave irradiation has been used for a rapid and efficient synthesis of quinoline-4-carboxylic acids 5a-g and 1,2,3,4-tetrahydroacridine-9-carboxylic acid (6) from the reaction of isatins 1-3 with acyclic and cyclic ketones in basic medium. 2-Hydroxyquinoline-4-carboxylic acid (11) was also obtained by irradiating a mixture of isatin 1 and malonic acid in AcOH. The esters of 5f and 11 and their respective hydrazides 8 and 13 were also prepared under MWI.
The invention relates to 3-aza-bicyclo[3.1.0]hexane derivatives of formula (I) wherein A, B, n, X, and R

are as described in the description, and salts thereof, and their use as orexin receptor antagonists.
