An efficient cross-coupling reaction of arylhalides and nitromethane was developed with the use of parallel microscale experimentation. The arylnitromethane products are precursors for numerous useful synthetic products. An efficient method for their direct conversion to the corresponding oximes and aldehydes in a one-pot operation has been discovered. The process exploits inexpensive nitromethane

A process for preparing isoxazole compounds of formula I:
in which a nitroaryl of the formula (II):
is contacted with an alkyl acetoacetate of the formula (III) or a salt thereof:
in the presence of an activating agent and a base to provide the isoxazole compound.
Chemical compounds of formula (I):
and pharmaceutically acceptable salts and addition compounds and prodrugs thereof are useful in therapy, particularly for the treatment of disorders of the central nervous system; damage to the central nervous system; cardiovascular disorders; gastrointestinal disorders; diabetes inspidus, and sleep apnea.
Fertility management can include: administering to the subject one or more doses of a compound according to Formula I so as to reduce fertility in the subject. Fertility management can also include administering an effective amount of the compound to: impair Sertoli cell function in a male subject; inhibit spermatogenesis in the subject; reduce testis weight in the subject; reduce ovary weight in a female subject; reduce serum progesterone in the female subject; impair ovarian follicle function in the female subject; causing reversible fertility in the subject. In order to return fertility, the method can include ceasing administration of the compound to the subject so as to return fertility in the subject. The compound can be administered for irreversibly sterilizing the subject.
