The tosyl group causes interference with mixed carbonic anhydride and p-nitrophenyl ester formation in certain instances. Several protected peptide sequences, occurring in the insulin molecule, and some tosylated p-nitrophenyl esters, have been prepared in the course of investigating this interference.
Four vasopressin analogues, modified in positions 2, 3 and 8 were prepared by solid phase as well as solution synthesis. Analogues, containing a D-amino acid in position 3, exhibit a low but markedly specific antidiuretic activity. Analogues with a D-substituent in position 2 show a more specific pressor activity.
