  Tetrapyrroles. IV. A highly efficient synthesis of homochiral dihydropyrromethenones via Pdo mediated coupling of iodopyrroles and acetylenic amides

  摘要：

  Homochiral dihydropyrromethenones of type 20 have been synthesized in a highly efficient manner by Pd(o) mediated coupling of iodopyrrole 14 with acetylenic amides 18, followed by F- catalyzed 5-exo-dig cyclization. In analogous fashion, phytochrome (8) precursor 25a has been prepared in 85% overall yield from iodopyrrole 22.

  Dihydropyrromethenone derivative 32b, which constitutes the A,B-ring segment of phytochrome (6), has been prepared in enantiomerically pure form beginning with acetylenic amide 47b and iodopyrrole 27. The key steps involved the TBAF-catalyzed 5-exo-dig cyclization of the acetylenic pyrrole 48b, followed by thia-Mitsunobu inversion of the resulting alcohol derivative 31b.
