The present invention relates to a compound of the general formula (I): STR1 wherein ring A is a benzene ring that may be substituted; Y is a divalent group as a constituent member of ring B forming a 5- to 8-membered ring; Q1 is a group of the formula --X--P(O)(OR1)(OR2) wherein X is a bond or a divalent group; R1 and R2, identical or different, are hydrogen or a lower alkyl, or may be combined together to form a ring; Q2 is hydrogen, a hydrocarbon group that may be substituted or a heterocyclic group that may be substituted; and the group of the formula --CON(Q1)(Q2) is connected to the a- or b-position carbon atom, or a salt thereof, which is useful as prophylactic and therapeutic agents of various metabolic bone diseases such as osteoporosis.

- Electron Paramagnetic Resonance Spectra of Substituted 1- and 2-Naphthylmethyl Radicals
-
The EPR spectra of 7-tert-butyl-1-naphthylmethyl and 6-tert-butyl-2-naphthylmethyl radicals, prepared by photolysis of the hydrocarbon with tert-butyl peroxide at -40 deg C, have been analysed by correlation methods: average α(C-H) coupling constants are 15.0 and 15.25 G respectively, in line with the expected relative stabilities of the two radicals and the recently reported stabilization energy for 1-naphthylmethyl.
