Abstract
Dimethylformamide–sulphur trioxide (DMF–SO3) complex was found to be more suitable for tyrosine sulphation than pyridine–sulphur trioxide (Pyr–SO3) complex, the most commonly used sulphur trioxide complex for sulphation. The work-up after sulphation using DMF–SO3 was also easier than with Pyr–SO3. The usefulness of DMF–SO3 complex was demonstrated through the synthesis of two tyrosine sulphate [Tyr(SO3H)]-containing peptides, leucine-enkephalin sulphate and leucosulfakinin-II.This publication has 33 references indexed in Scilit:
