The nucleophilic addition of sodium acetylide to 1,3-diketonates derived from 1-aryl-4,4,4-trifluorobutane-1,3-diones is reported. Tertiary 1,4-alkynediols containing CF3 and aroylmethyl groups are synthesized. 5,5′-Diaryl-3,3′-bis(trifluoromethyl)-2,2′-bifurans are prepared via a novel double cyclization of these alkynediols.
据报道,将乙炔酸钠亲核加成到由1-芳基-4,4,4-三氟丁烷-1,3-二酮衍生的1,3-二酮酸酯中。合成含有CF 3和芳酰基甲基的叔1,4-炔二醇。通过这些炔二醇的新型双环化制备5,5'-二芳基-3,3'-双(三氟甲基)-2,2'-二呋喃。
