α-ketoglutarate-dependent dioxygenases that are capable of hydroxylating free-standing glutamine at its C3 and C4 position respectively. In particular, the C4 hydroxylase, Q4Ox, catalyzes the reaction with approximately 4,300 total turnover numbers, facilitating synthesis of a solid-phase compatible building block and stereochemical elucidation at the C4 position of the hydroxylated product. This work will enable the
A new method for the synthesis of threo-ß-hydroxy-L-glutamine consists of epoxidation of (S)-3-benzyloxycarbonyl-5-oxo-4-vinyltetrahydro-1, 3-oxazole (protected L-vinylglycine) and regioselective ring cleavage.
