Abstract

Derivatives of .alpha.,.alpha.-trehalose-6,6'-fatty acid diester having phosphoric ester groups in the molecule which are useful as a carcinostatic agent. One of the derivatives may be prepared by reacting diphenylphosphoryl chloridate with a derivative of 2,3,2',3'-tetra-O-benzyl-.alpha.,.alpha.-trehalose-6,6'-fatty acid diester. Another derivative may be obtained by substituting benzyl groups at 2,3,2',3' positions of trehalose with hydrogen atoms.
