Unexpected products from the Fp2-catalyzed reductive cyclization of nitroaromatics bearing pendant unsaturation
摘要:
A representative o-nitroenone (Z=O) was cyclized by reduction with CO and [CpFe(CO)(2)](2) (FP2) as the catalyst to give the corresponding 4-quinolone. In contrast, Baylis-Hillman adducts derived from o-nitrobenzaldehydes were cyclized to N-formylindolines and indoles under the same conditions. (C) 2003 Published by Elsevier Science Ltd.
