Hydroxy-group directing hydroiminoacylation of α,ω-dien-3-ol with aidimine by Wilkinson's Complex

Add time:07/25/2019    Source:sciencedirect.com

Ferrocenecarboxaldimine (1) reacted with 1,4-pentadien-3-ol (2) under Wilkinson's catalyst (3) to give the hydroacylated product 6 after hydrolysis of the resulting ketimine 4. Prolonged reaction time induced the isomerization of 6 to 7. When 1,5-hexadien-3-ol (11) was used, the hydroiminoacylation of the allyl alcohol group gave predominantly 12, which showed a remarkable hydroxy-group directing effect.
