Chromanone derivatives of the formula I ##STR1## in which R.sup.1 to R.sup.4 are each, independently of one another, H, A, CN, Hal, OR.sup.5, COOR.sup.5, CF.sub.3, OCF.sub.3, NO.sub.2, Ar, OAr, N(R.sup.5).sub.2 or CON(R.sup.5).sub.2, R.sup.5 is H or A, A is alkyl having 1 to 6 carbon atoms, Ar is phenyl which is unsubstituted or substituted by A, OR.sup.5, CN, Hal, CF.sub.3, OCF.sub.3, NO.sub.2 or N(R.sup.5).sub.2, Hal is F, Cl, Br or I, and their salts, are suitable as intermediates in the synthesis of medicaments.
