A Straightforward Approach to MMP‐2 and MMP‐9 Inhibitors Based on Chelate Claisen Rearrangements

Abstract

The chelate Claisen rearrangement is a versatile tool for the stereoselective synthesis of β‐substituted γ,δ‐unsaturated amino acids, which can be converted into β‐substitutedaspartates by oxidative cleavage. These are ideal precursors for the synthesis of hydroxamate‐type MMP inhibitors.
