    • 1=0.049 and Rw=0.1185 for 4576 observed reflections. Due to the change in the conformation of the 'chromeno' ring the independent molecules A and B differ, which is indicated by the difference in the torsion angles C14C15C16O1 (-144.6(5)) and C30C31C32O3 (-157.1(4)), respectively. The phenolic OH of A showed an intermolecular hydrogen bonding with the hydroxyl oxygen of B. Crystallographic data (excluding structure factors) for 3e have been deposited with the Cambridge Crystallographic Data Centre as supplementary publication numbers CCDC 644669.

    • 4e While intermediacy of a similar species cannot be ruled out in the present case we, however, failed to detect or isolate a corresponding carbaldehyde intermediate under the condition employed during our synthesis of compound 3. Preparation of this intermediate from 1a for further studies was also not successful.

    • note
    • 4d The beta-amino imine, when protonated, would be able to undergo ring-closure and then subsequent aromatization to give compound 3 with regeneration of the 'second' 2-aminophenol molecule. We thank the reviewer for bringing this to our notice.{A figure is presented}
