A novel stereoselective synthesis of (Z)-3-iodo-3-alken-1-one from 2-alkyn-1-one
摘要:
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.
