Total synthesis of (±)-phytochromobilin starting from two pyrrole derivatives

(±)-Phytochromobilin was synthesized as an acid form by developing a convenient method for the preparation of A- and D-rings starting from a 2- tosylpyrrole derivative, followed by efficient construction of A/B- and C/D- ring components via Wittig-type coupling reaction of 5-tosylpyrrolinones with 2-formylpyrrole, and palladium catalyzed deprotection of allyl esters of propanoic acid side chains at C-8 and C-12.
