A series of p-benzoquinone derivatives having one or two carbamoyloxyalkyl groups in the 2 and/or 5-positions were synthesized and evaluated as antileukemic agents. Among these compounds 2, 5-bis (1-aziridinyl)-3-(2-carbamoyloxyethyl)-6-methyl-p-benzoquinone (21) showed high activity against lymphoid leukemia L-1210 in BDF1 mice.
