When treated with sodium hydride in dimethoxyethane, some γ-(acyloxy)-β-keto phosphonates react to give 2(3H)-furanones via an unexpected rearrangement which proceeds with carbon-carbon bond formation.Several possible mechanisms for this transformation have been tested through crossover experiments, rearrangement of an isotopically labeled substrate, and synthesis of a model intermediate.Results from these experiments allow elimination of several potential reaction pathways from further consideration and suggest a focus for future studies.

The invention discloses a volution lactone compound. The chemical structural formula of the volution lactone compound is shown in the specification. A preparing method of the volution lactone compound includes the steps that (1) cyclopentanone serves as a raw material and is subjected to a cyanohydrintion reaction, then cyano groups are hydrolyzed and esterified, and hydroxyl-cyclopentanecarboxylic acid ethyl ester is obtained; (2) a sulfonation reaction is carried out; (3) a butt joint ring formation reaction is carried out; (4) an alkylation reaction is carried out, wherein the cyclizing product obtained in the step (3), a reaction solvent and a catalyst are mixed, 3-bromopropylene is added into the mixed liquid, the solvent is removed in a pressure-reduction mode after reacting, water and benzene are added, extracting and layering are carried out, an organic phase substance is obtained, solvent pressure-reduction removing and filtering are carried out, and the final product volution lactone compound is obtained. The volution lactone compound has the advantage that a pesticide good in pest killing effect, long in lasing period and low in toxicity is obtained.

Paragraph 0260, (2014/09/29)
Described are compounds of Formula 1 which find utility in the treatment of cancer, autoimmune diseases and metabolic bone disorders through inhibition of c-FMS (CSF-1R), c-KIT, and/or PDGFR kinases. These compounds also find utility in the treatment of other mammalian diseases mediated by c-FMS, c-KIT, or PDGFR kinases.
