Towards the semi-synthesis of didemnin M. solution and solid phase synthesis of the pseudotetrapeptide: pGlu-Glnψ[COO]Ala-Pro-OH

Two approaches, solution and solid phase syntheses, were developed for the synthesis of the pseudotetrapeptide, pGlu-Glnψ[COO]Ala-Pro-OH. Both approaches gave comparable synthetic yields, but the latter approach provided an expedient entry to the synthesis of the target compound with higher product purity.
