report describes a new synthetic methodology for the ortho-arylation of arylamines and α-aromatic amino acids (phenylglycine and phenylalanine) through a Pd-catalyzed C(sp2)–Hactivation using the synthetic transientdirectinggroup diethoxyethyl-L-proline (DEP). A catalytic amount of diethoxyethyl-L-proline is sufficient to form mono-arylated arylamines as the major products using aryliodides. This

The present invention provides a compound which functions as a selective vitamin D receptor modulator and has action-selectivity or tissue-selectivity such that it does not induce hypercalcemia but causes other effects. There is provided a compound represented by formula (I), a solvate thereof or a prodrug thereof.
wherein m and n each independently represent 1 or 0;
R represents a hydrogen atom or an alkyl group;
Y represents an ethane-1,1-diyl group or an ethyne-1,2-diyl group; and
Z
1
represents a hydrogen atom and Z
2
represents a hydroxyalkoxy group, or
Z
1
and Z
