Reaction of iodoarenes and diethyl 2-pentenedicarboxylate under the Heck reaction conditions. Formation of 3-aryl-2-pentenedicarboxylates

Padmanabhan,Gavaskar,Triggle

, p. 3109 - 3113 (2007/10/03)

Various substituted iodoarenes underwent arylation with diethyl 2-pentenedicarboxylate under the Heck reaction conditions to give the expected diethyl 3-aryl-2-pentenedicarboxylates. Extension of this reaction to 2-iodoaniline gave the hitherto unreported ethyl quinolin-2-one-4-acetate.
