    摘要:The invention relates to an optimized synthesis of pregabalin and additional 4-aminobutane acids using an improved method for producing conjugated nitroalkenes. This is achieved by a nitro-aldol reaction of an aliphatic aldehyde with a nitroalkane in the presence of a suitable diamine directly followed by an elimination of the conjugated nitroalkene by adding an acid, a subsequent catalyzed asymmetrical 1,4-Michael addition of a suitable nucleophile, and a subsequent retro-Claisen reaction or a hydrolosis and decarboxylation with a concluding reduction to 4-aminobutane acid.

    标题 :Method of making teprenone
    发明人：SAUCY GABRIEL G
    摘要:The invention is directed to an efficient and economical method of making teprenone. Teprenone is synthesized by converting geranylgeraniol to teprenone by a novel route. The method of synthesis can begin with geranylgeraniol obtained from a biological source such as fermentation of a microorganism capable of producing geranylgeranyl or enzymatic synthesis in a cell free system to produce predominantly the 5E isomer of teprenone. The chemical synthesis proceeds with retention of configuration such that the teprenone produced has the isomeric configuration of the geranylgeraniol starting material.
