This invention relates to a novel class of hydroxamic acid based collagenase inhibitor derivatives of the formula
wherein R' is C1-C6 alkyl; R2 is C1-C6 alkyl, benzyl, hydroxybenzyl, benzyloxybenzyl, (C1-C6 alkoxy)benzyl, or ben- zyloxy(C1-C6 alkyl); a is a chiral center with optional R or S stereochemistry; A is a
group or a -(CR3 = CR4)- group wherein b and c are chiral centers with optional R or S stereochemistry; R3 is hydrogen, C1-C6alkyl, phenyl, or phenyl (C1-C6 alkyl); and R4 is hydrogen or C1-C6 alkyl, phenyl (C1-C6 alkyl), cycloalkyl, or cycloalkyl (C1-Cealkyl). The invention further relatesto pharmaceutical compositions containing such compounds for the treatment of collagenase induced diseases.
