3,6‐Diarylidene‐2,5‐piperazinediones ( 2 ) and 3‐alkylidene‐6‐arylidene‐2,5‐piperazinediones ( 6 ) were synthesized from diacetyl‐2,5‐piperazinedione ( 1 ) under solid‐liquid phase transfer catalytic conditions. 2 could be easily convered to α‐amino acid by reducing with zinc powder and hydrolyzing with concentrated hydrochloric acid. The effect of different phase transfer catalysts and reaction conditions were studied.
