ABSTRACT
An improved scalable synthesis of orthogonally functionalized methoxyaspartate, the chiral hinge region element in cystobactamids, is reported. This improvement sets the stage for the total synthesis of four new cystobactamids along with cystobactamid 861-2, whose antibacterial properties are determined and compared. The cyano derivative of cystobactamide 861-2 shows superior antibacterial activity against Gram-negative bacteria to any natural cystobactamide tested so far.
