Benzene Ring In A Substituent E Patents (Class 564/211)
  • Patent number: 8901352
    Abstract: We have developed a new method for the synthesis of Rasagiline (Formula 1) based on the alkylation of trifluoroacetyl protected aminoindan. This protection enabled us to carry out an alkylation of aminoindan with a high yield and purity under very mild conditions with a wide range of reaction conditions and reagent selection. Considering the ease, purity and high yields of introducing and removal of the trifluoroacetyl group, this approach is a highly practical and economical way for the synthesis of rasagiline or its pharmaceutically acceptable salts.

  • Patent number: 5352832
    Abstract: The present invention comprises a process for the asymmetric synthesis of florfenicol, thiamphenicol or chloramphenicol, from a derivative of trans-cinnamic acid, comprising the steps:(a) converting the acid to an acid chloride using a chlorinating agent, and reducing the acid chloride to a trans allylic alcohol with a reducing agent;(b) asymmetrically epoxidizing the allylic alcohol of step (a), by reacting with t-butylhydroperoxide in the presence of a chiral epoxidation catalyst prepared from titanium (IV) isopropoxide and L-diisopropyltartaric acid, to form a chiral epoxide;(c) regioselectively opening the epoxide of step (b) by sequentially treating with sodium hydride, zinc chloride and dichloroacetonitrile to form an oxazoline;(d) stereoselective inversion/isomerization of the oxazoline of step (c) by sequentially treating with: (i) a lower alkylsulfonyl chloride and a tertiary amine base; (ii) sulfuric acid and water; (iii) an alkali metal hydroxide; to form an oxazoline;(e) optionally treating the ox
