DBU-Mediated Diastereoselective C3-Quaternary Alkylation of Cyclic Dipeptides
{{output}}
A mild and highly diastereoselective strategy for the direct C3-quaternary carbonation of cyclic dipeptides (CDPs) has been explored using DBU as a base. This approach enabled the efficient functionalization of the C3 position in CDPs that contain a C6 chiral ... ...
