Synthesis of 1,2,3,7,8,9-hexahydrodipyrrins and secocorrins: important precursors for the construction of corrins.
[formula: see text] Hexahydrodipyrrins 15 (X=H2) have been prepared by two routes: Pd(0)-initiated coupling/cyclization of triflates 11 and alkyne amines 12 and reduction of semicorrins 26 (X=O).
