Total syntheses of phycocyanobilin derivatives bearing a modified A-ring toward the structure/function analysis of phytochrome
Phycocyanobilin (PCB) derivatives bearing a modified A-ring, including 3,3'-dihydrogenated PCB derivatives, were efficiently synthesized in free acid forms by applying our original methods for the preparation of A-, A/B-, and C/D-ring components toward the structure/function analysis of phytochrome.
