Total syntheses of physocyanobilin and its derivative bearing a photoreactive group at the D-ring accomplished by developing a new and efficient method for the construction of A,B-rings component, which consists of the Wittig-type new coupling reaction of 4-(1-methoxyethyl or 1- tosylethyl)-3-methyl-5-tosyl-1,5-dihydro-2H-pyrrol-2-one and a 2-formyl pyrrole derivative in the presence of (n)Bu3P and a base, followed by reduction with aluminum amalgam and a subsequent acid or base treatment.

C/D-Ring components of phycobilin derivatives bearing a photoreactive group at D-ring were regioselectively synthesized by applying our original synthetic reactions such as acid-catalyzed rearrangement of 2-tosyl group of 3,4-disubstituted 2-tosylpyrroles
