The TTN phenolic oxidation, along with the N-protective group of the corresponding tripeptide derivatives, was examined to accomplish construction of a cyclic isodityrosine derivative under solid-phase conditions. The desired cyclization was effected under the TTN (thallium(III) trinitrate)/NMP-MeOH

A novel solid-phase synthetic method for dehydroalanines and dehydropeptides has been developed. Elimination of the sulfone part with concomitant release from the solid support afforded the desired dehydroalanine derivatives. The products were given in good yields and excellent purities.
A dihydropyran carboxylic acid type linker is suitable for the solid phase Suzuki type aryl-aryl coupling reaction for the preparation of various biphenyltetrazole derivatives.
