Iodine-Initiated Domino Reaction of Hepta-1,2-dien-6-yn-4-ols and Brønsted Acid Promoted Cyclization of Hepta-1,2,6-trien-4-ols Leading to Functionalized Benzenes.

Buy one get one free: Concurrent introduction of both iodo ‐ and carbonyl groups, along with the construction of the benzenoid core, has been achieved through an iodine ‐ initiated domino reaction of hepta ‐ 1,2 ‐ dien ‐ 6 ‐ yn ‐ 4 ‐ ols. Moreover, cyclization of hepta ‐ 1,2,6 ‐ trien ‐ 4 ‐ ols turns out to also be an efficient pathway toward diversely substituted benzenes. [ABSTRACT FROM AUTHOR]
