The invention relates to 3-hydroxy-and 3-keto-cyclohetero-substituted leucine compounds that are inhibitors of cysteine proteases, particularly cathepsin K, and are useful in the treatment of diseases in which inhibition of bone loss is a factor. The 3-hydroxy-or 3-keto-moiety is bonded to a tetrahydrothiophene, tetrahydrothiopyran, tetrahydrofuran or tetrahydropyran ring.
