Article abstract of DOI:10.1016/0040-4039(95)00743-V

Methylene piperazine-2,5-diones 5a and 5b are important synthetic intermediates. The preparation as well as the use of these compounds in the synthesis of amino acid derivatives are described. Our studies demonstrate that excellent chiral induction in car
