Abstract
The disclosure relates to the synthesis of amide containing compounds inflow. In particular, the disclosure relates to the synthesis of polypeptides via native chemical ligation inflow. The disclosure also relates to selective desulfurization or deselenization of amide containing compounds comprising a thiol, disulfide, selenol or diselenide functional group respectively, particularly polypeptides.
Claims28
A method of preparing an amide containing compound in flow comprising the step of reacting:
- (i) an ester, with
- (ii) a molecule comprising a terminal amino acid selected from the group consisting of cysteine, cystine, a thiol-derivatized amino acid, a disulfide-derivatized amino acid, selenocysteine, selenocystine, a selenol-derivatized amino acid, and a diselenide-derivatized amino acid;
- wherein the ester is a thioester or selenoester.
