A novel and highly efficientcyclization method has been developed to access a new class of cyclic carbo-isosteric depsipeptides and carbo-isosteric peptides. Our strategy requires easily accessible C-terminal methyl ketoneester or amide functionalized linear precursors as starting materials. The well-known reductive amination has then been used to afford cyclic tetra- to octa-pseudopeptides via a
A preparative protease-catalyzed peptide synthesis in biphasicaqueous-organicsystems is described. This approach using both free as well as immobilized proteases as catalysts provides high yields and includes the possibility to re-utilize the enzymes.
