General Access to Modified alpha-Amino Acids by Bioinspired Stereoselective gamma-C-H Bond Lactonization
alpha-Amino acids represent a valuable class of natural products employed as building blocks in biological and chemical synthesis. Because of the limited number of natural amino acids available, and of their widespread application in proteomics, diagnosis, drug delivery and catalysis, there is an increasing demand for the development of procedures for the preparation of modified analogues. Herein, we show that the use of bioinspired manganese catalysts and H2O2 under mild conditions, provides access to modified alpha-amino acids via gamma-C-H bond lactonization. The system can efficiently target 1 degrees, 2 degrees and 3 degrees gamma-C-H bonds of alpha-substituted and achiral alpha,alpha-disubstituted alpha-amino acids with outstanding site-selectivity, good to excellent diastereoselectivity and (where applicable) enantioselectivity. This methodology may be considered alternative to well-established organometallic procedures.
