Toward the synthesis of biologically important chlorins, isobacteriochlorins, and corrins. Cyclic enamides from acetylenic amides

Jacobi, Peter A.,Brielmann, Harry L.,Hauck, Sheila I.

, p. 5013 - 5023 (2007/10/03)

Cyclic enamides 1 of a type useful in the synthesis of naturally occurring chlorins, isobacteriochlorins, and corrins have been prepared by a process involving 5-exo-dig cyclization of the appropriate acetylenic amides 11. The desired cyclization is catalyzed by either n-Bu4NF or LiAl-(NHBn)4.
