Abstract

The invention discloses a synthesis method for spiral indole compounds based on sarcosine and multi-carbonyl-class cyclic ketone compounds. The method comprises the steps that pyridyl-class indole compounds, sarcosine and multi-carbonyl-class cyclic ketone compounds are subjected to addition and condensation reaction in an alcohol aqueous solution, high-yield spiral indole compounds are obtained,and then extraction filtration and recrystallization are conducted to obtain purified products. Compared with the prior art, the synthesis method is simple and convenient, original multi-step reactionis replaced by a single-pot synthesis method, raw materials are easily obtained, the reaction efficiency is high, and the method is suitable for various reaction substrates; the spiral indole compounds have the drug activity at the same time and can be applied to clinical drugs capable of effectively treating tumors and cancer.

Description

technical field [0001] The invention belongs to the field of organic synthesis, and in particular relates to a synthesis method and application of a helical indole compound based on sarcosine and polycarbonyl cyclic ketone compounds. Background technique [0002] It has been reported that spirooxindole compounds can be used as inhibitors of P53-MDM2. These small molecular compounds can be used as a drug for tumor treatment, directly targeting tumor cells without affecting normal cells. In the past few years, major advances have been made in synthetic methods to obtain helical indole derivatives in a manner that simultaneously creates a chiral quaternary carbon center. For example, Overman reported an asymmetric intramolecular Heck reaction to synthesize spiro-pyrrole-3,3'-indole] derivatives with high enantioselectivity; (references V.Caprio, B.Guyen, Y. Opoku-Boahen, J. Mann, S.M. Gowan, L.M. Kelland, M.A. Read and S. Neidle, Bio. Med. Chem. Lett., 2000, 10, 2063-2066.) ...
