Synthesis of 1,2,3,7,8,9-Hexahydrodipyrrins and Secocorrins: Important Precursors for the Construction of Corrins
摘要:
[GRAPHICS]Hexahydrodipyrrins 15 (X = H-2) have been prepared by two routes: Pd(0)-initiated coupling/cyclization of triflates 11 and alkyne amines 12 and reduction of semicorrins 26 (X = 0).
