ketone-based three-componentreactions have been established for the stereoselectivesynthesis of functionalized electron-deficient trans-cyclopropanes. The multicomponent reactions were conducted by reacting readily available and inexpensive starting materials under microwave irradiation. The procedures are very facile, highly stereoselective, and avoids the use of ylides. multicomponent reactions - cyclopropanes

A Yb(OTf)3-mediated annulation of cyclopropane-1,1-dicarbonitriles and 2-aminobenzaldehydes for the synthesis of polysubstitutedquinolines in generally good yields was investigated. In the cascade reaction, the protocol includes ring opening, intermolecular nuclophilic addition, intramolecular nuclophilic addition, and demalononitrile aromatization, in which the malononitrile group serves as a deciduous
