journal contribution
posted on 2002-09-14, 00:00 authored by Vijay Nair, D. Sethumadhavan, Smitha M. Nair, Nigam P. Rath, Guenter K. EigendorfHighly substituted tropone derivatives were
obtained as a result of SnCl4-catalyzed cycloaddition of
3-methoxy-substituted o-benzoquinones with aryl acetylenes
and subsequent rearrangement of the adducts with concomitant decarbonylation.
