Amine-catalyzed (3+n) annulations of 2-(acetoxymethyl)buta-2,3-dienoates with 1,n-bisnucleophiles (n = 3-5).
A tertiary amine-catalyzed formal (3+n) annulation of 2-(acetoxymethyl)buta-2,3-dienoate with 1,n-binucleophiles has been developed, which provides a facile entry to heterocyclic compounds. The mechanism, involving tandem S(N)2'-S(N)2' substitution and Michael addition, has also been established.
