A one-pot reaction of 2-alkyn-1-one with sodium iodide/acetonitrile/ttimethylsilyl chloride/water or trimethylsilyl iodide/acetonitrile at 25 degrees C gave almost exclusively (Z)-3-iodo-3-alken-1-one in good yields.
Palladium-Catalyzed Tandem Cyclization and Dimerization of (<i>Z</i>)-3-Iodo-3-alken-1-ones
The use of palladacycle catalyst to the transformation of various (Z)-beta-iodo-beta,gamma-enones into the corresponding 2,5-disubstituted furans in good yields at room temperature was described. The comparison of using other kind of palladium catalysts under the similar reaction conditions was also described. (C) 1998 Elsevier Science Ltd. All rights reserved.
