Three-Component Stereoselective Synthesis of (1R,2S)-1-Aryl-2-{[prop-2-yn(en)yloxy]methyl}spiro[2,4]hepta-4,7-diones

Аннотация

Three-component reaction involving cyclopentane-1,3-dione, substituted benzaldehydes, and chloromethyl propyn(en)yl ethers results in a stereoselective formation of trans-1-aryl-2-{[prop-2-(yn)enyloxy]-methyl}spiro[2,4]hepta-4,7-diones in satisfactory yields.
