摘要:Improved process for the synthesis of (S)-pregabalin having more than 99% ee through (S) 3-cyano-5-methyl-hexanoic acid has been developed. In addition to above, a novel process for resolution of ( RS ) - 3-cyano-5-methyl-hexanoic acid through diastereomeric salt formation with cinchonidine to obtain ( S ) - 3-cyano-5-methyl-hexanoic acid in high yield and high optical purity has been developed and furthermore process for recovery/ reuse of cinchonidine is also developed to improve the overall process efficiency.

摘要:The present invention relates to synthesis of carboxy group terminated di-unsaturated ketones having C=C double bonds at the α,β and γ,δ position or at the β,γ and γ,δ position relative to the carbonyl carbon atom. These ketones can be obtained easily and in few steps from respective alkynols having a terminal carboxyl group. These ketones are important key building block for the synthesis of derivatives of isoprenoids, especially of vitamin E.

摘要:The present invention relates to synthesis of specific allylic alcohols having terminal carboxyl groups based on steps of ethynylation and hydrogenation in the presence of a Lindlar catalyst. These allylic alcohols are particularly useful to offer pathways to syntheses of isophytol or tocopherols having a terminal carboxyl group by a very small number of reactions steps.
