超声介导的无催化剂合成6 H -1-苯并吡喃并[4,3- b ]喹啉-6-酮类化合物,导致新的喹啉衍生物:作为潜在抗癌药的评估
摘要:
通过4-氯-2-氧代-2 H的反应可轻松合成无催化的6 H -1-苯并吡喃并[4,3- b ]喹啉-6--苯甲基-3-甲醛与各种芳香胺在超声波的作用下。这些化合物中的一些被转化为相应的2-(3-(羟甲基)喹啉-2-基)苯酚,并给出了代表性喹啉衍生物的进一步结构详述。通过单晶X射线衍射研究证实了两种代表性化合物的分子结构。评估了其中许多化合物在体外对四种癌细胞系的抗增殖特性,发现几种化合物具有活性。进一步的体外研究表明,抑制沉默调节蛋白可能是这些分子起作用的可能机制。
An environmentally-benign electrochemical approach for the construction of quinoline derivatives employing N,N-dimethylformamide (DMF) as the methine source has been devised by cyclization of 4-(phenylamino)-2H-chromen-2-ones. In a user-friendly undivided cell, 6H-chromeno[4,3-b]quinolin-6-ones were obtained under chemical oxidant-free and transition-metal-free conditions in 43–92% yields with high

ortho-(Phenylpropioloxy)benzonitrile sulphide, generated in situ by thermal decarboxylation of the oxathiazolone (1), undergoes intramolecular 1,3-dipolar cycloaddition forming the chromenoisothiazole (4a); ortho-cinnamoylbenzonitrile sulphides also yield (4), together with nitrile, chromenoquinoline and amino-chromene by-products.

The synthesis of polycyclic heteroaromatic compounds using the reaction of a quinone-methide, generated in situ, with an aromatic amine has been successfully extended using quinone-methides of coumarin and of pyridones. Preliminary studies with the benzenoid quinone-methide (33) have so far proved to give only low yields of the expected acridines. Generation of ‘quinone-methides’ in which the carbonyl
