A novel method for Fmoc/tBu solution-phase peptide synthesis and the development of a new benzyl-type group-assisted purification (GAP) protecting group is reported. This GAP protecting group is utilized in place of a polymer support, facilitating C→N Fmoc peptide synthesis without chromatography or recrystallization. The GAP group can be added and removed in high yield, and was used to synthesize over 1 gram of the immunostimulant, thymopentin, in high overall yield (83 %) and purity (99 %). Fmoc/tBu solution-phase peptide synthesis and the development of a new benzyl-type group-assisted purification (GAP) protecting group is reported. This new GAP protecting group replaces a polymer support, facilitating C→N Fmoc peptide synthesis without chromatography or recrystallization. Over 1 gram of the immunostimulant, thymopentin, was synthesized in high overall yield (83 %) and purity (99 %).

We present a novel and highly efficient methodology that allows for the construction of C-P bonds via the palladium-catalyzed air-based oxidative coupling of various commercially available arylboronic acids with easily oxidized H-phosphine oxides leading to valuable aryl phosphine oxides, particularly triarylphosphine oxides, with the use of air as the green oxidant, broad substrate applicability and good to excellent yields. The described catalytic system should be an efficient complement to the Chan-Lam type reaction and be useful in synthetic programs. This journal is the Partner Organisations 2014.
