Synthesis, molecular structure and spectroscopic investigations of novel fluorinated spiro heterocycles.
This paper describes an efficient and regioselective method for the synthesis of novel fluorinated spiro-heterocycles in excellent yield by cascade [5+1] double Michael addition reactions. The compounds 7,11-bis(4-fluorophenyl)-2,4-dimethyl- 2,4-diazaspiro[5.5] undecane-1,3,5,9-tetraone (3a) and 2,4-dimethyl-7,11-bis (4-(trifluoromethyl)phenyl)-2,4-diazaspiro[5.5]undecane-1,3,5,9-tetraone (3b) ...
متن کاملMontmorillonite Ksf Catalyzed Facile Synthesis of Novel Spiro Heterocycles under Microwave Irradiation
The arylidienes of spiro thiazolidines (5) containing α,β-unsaturated function have been used as component of Micheal addition with equimolar amount of 2-aminopyridine (6a) to give novel spiro [indole-3,2′-pyrido[1,2-a]thiazolo[5,4-e]pyrimidines] (7) in a single step under microwaves in presence of montmorillonite KSF as solid support. The new improved synthetic method for spiro [indole-3, 2′-t...
متن کاملSynthesis and Spectroscopic Characterization of a Series of New Anthralin Derivatives and Their Corresponding Spiro-Hetherocycles
Several 10-substituted anthralins were readily prepared. Their oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone gave the corresponding novel heteroatomic systems. All derivatives were fully characterized by IR, Mass and 1HNMR spectroscopy.
