Novel compounds I (R1 = a mono or bicyclic C1-C9 heterocyclic group containing from 1 to 3 heteroatoms chosen from N, O and S, a phenyl group, a C3-C6 cycloalkyl group, or a C3-C6 cycloalkenyl group, each of which may optionally be substituted; R2 = a mono or bicyclic C1-C9 heterocyclic group containing from 1 to 3 heteroatoms chosen from N, O and S, or a phenyl group, each of which may optionally be substituted; R3 = H, F, CN or an optionally substituted C1-C6 alkyl group, m is 0, 1 or 2; and n is 0, 1 or 2) are antagonists selective for the metabotropic mGlu5 receptor, useful for the treatment of neuromuscular dysfunction of the lower urinary tract in a mammal. Further uses include the treatment of migraine; gastroesophageal reflux disease (GERD); anxiety disorder; abuse, substance dependence and substance withdrawal disorder; neuropathic pain disorder; and fragile X syndrome disorders.

Abstract The 2-isoxazohes and isoxazole functionalized with phosphonate group were synthesized by the 1,3-dipolar cycloaddition reaction of nitrile oxides with various unsaturated phosphonates.
The catalytic acetoxylation of dialkyl allyl phosphonates with the Pd(OAc)2/benzoquinone/MnO2/HOAc system leads, regioselectively, to dialkyl 3- acetoxy 1-alkenyl phosphonates. On the basis of the regio- and stereoselectivity of the reaction, a mechanism is proposed which involves a (π-allyl) palladium complex as intermediate.
