Abstract: The present invention provides improved methods for the chemical synthesis of methylene malonates using the Knovenagel synthesis reaction. The method of the invention provides for improved methylene malonates by significantly reducing or eliminating the formation of alternative and/or deleterious side products, significantly reducing or eliminating unwanted consumption of methylene malonates, and significantly reducing or eliminating the degradation of methylene malonates. These advantages result in methylene malonates, which upon recovery, are of higher quality, greater purity, improved yield and possess overall improved performance characteristics (e.g., improved cure speed, retention of cure speed, improved shelf-life and/or stability).

The method is characterized in that a phosphine-borane compound represented by the following general formula (1) is subjected to a deboronation reaction, followed by lithiation, then the reaction product is subjected to reaction with an alkyldihalogenophosphine represented by RaPX?2, and thereafter the reaction product is subjected to reaction with a Grignard reagent represented by RbMgX? to produce an optically active 1,2-bis(dialkylphosphino)benzene derivative (A). R1 and R2 respectively represent an alkyl group having 1 to 8 carbon atoms, and the number of carbon atoms is different between R1 and R2. Ra is either R1 or R2 and Rb is the other of R1 and R2. X, X?, and X? each represent a halogen atom.

Abstract: (S)-(+)-3-(aminomethyl)-5-methyl-hexanoic acid or (S)-pregabalin is an anticonvulsive drug. In addition to its use as an anticonvulsive agent, pregabalin has also been indicated as a medicament in the treatment of anxiety, neuropathic pain and pain in patients with fibromyalgia. Provided herein are thioester intermediates in the synthesis of and processes for the synthesis of 3-(aminomethyl)-5-methyl-hexanoic acid in the (R) or (S) configuration.
