The synthesis of d-cycloserine has been successfully accomplished from the readily available d-serine through three simple and efficient routes. In each synthetic strategy, cyclization reactions are involved as the key step, and one-pot processes are employed. The simple treatment and mild reaction conditions are attractive features in this methodology.
A simple pathway for the preparation of D‐cycloserine is presented. The intermediates and D‐cycloserine were characterized by FT‐IR, 1H‐NMR spectra and elemental analysis. D‐Cycloserine can inhibit the growth of Mycobacterium tuberculosis and can be used as a second‐line drug for the treatment of tuberculosis, especially for the use in developing countries.
