Definitions

  • the present invention relates to optically active dihydroxy hexanoate derivatives of formula Ila and more particularly to compounds of formula II which are useful intermediates for the synthesis of HMG-CoA enzyme inhibitors like atorvastatin, cerivastatin, rosuvastatin, pitavastatin, fluvastatin. BACKGROUND OF THE INVENTION
  • Ri and R 2 are independently chosen alkyl of one to three carbons and R 3 is alkyl of from 1 to 8 carbon atoms, alternatively compounds of formula la,
  • ⁇ and R 2 are independently chosen from alkyl of one to three carbons, phenyl or Ri and R 2 taken together as - (CH2)n- wherein n is 4 or 5 and R 3 is alkyl of from 1 to 8 carbon atoms and also compounds of Formula lb
  • R x and R 2 are alkyl of from 1-5 carbons and R 3 is as defined above is a valuable structural element for synthesizing compounds, which are known as ant hypercholesterolemic agents having an inhibitory effect on HMG-CoA reductase.
  • EP 0 319 847 describes a process for the preparation of compounds of formula 1 starting from L-Malic acid. This process, however, suffers from the fact that the process is not industrially scalable and also possesses purification problems due to the non- crystalline nature of the intermediates.
  • US 5,998,633 describes a process for the preparation of protected esters of 3,4-dihydroxy butyric acid from a carbohydrate moiety which is transformed into the desired 3,4-dihydroxy butanoic acid derivatives in about 4 steps.
  • the 3,4-dihydroxy butanoic acid derivative is then functionalized into compounds of formula I involving a multiple number of steps.
  • Ar ' unsubstituted or substituted aryl or heteroaryl
  • R 3 alkyl from 1 to 8 carbons, aryl or aralkyl
  • the present invention also provides for a process for the manufacture of compounds of formula II
  • Ar unsubstituted or substituted aryl or heteroaryl
  • R 3 alkyl from 1 to 8 carbons, aryl or aralkyl which comprises of:
  • the compound of formula II is oxidized to a compound of formula VIII, where R 3 is alkyl from 1 to 8 carbons, aryl or aralkyl and Ar is unsubstituted or substituted aryl or heteroaryl using pyridinium chloro chromate or DMSO/oxalyl chloride.
  • Formula IX The compound of formula IX is further converted to a compound of formula VII, where R 3 is alkyl from 1 to 8 carbons, aryl or aralkyl, Ar is unsubstituted or substituted aryl or heteroaryl.
  • Compound of formula II serves as a good intermediate for the synthesis of important substrates, which are useful in the synthesis of statins.
  • Compound of formula II can be converted into a facile leaving group by treating with tosyl chloride, methane sulfonyl chloride and the resulting intermediate can be displaced with cyanide to give compounds of formula VII.
  • Compound of formula II can be converted to formula IX by reacting with aqueous HBr solution or by reaction with triphenyl phosphine and CBr 4 which is then converted to compound of formula VII.
  • Compound of formula II can be oxidized using standard procedures to give a compound of formula VIII.
  • the present invention relates to optically active dihydroxy hexanoate derivatives of formula Ila which are useful intermediates for the synthesis of HMG-CoA enzyme inhibitors like atorvastatin, cerivastatin, rosuvastatin, pitavastatin, fluvastatin.
  • Example 4 Synthesis of tert-Butyl 6-triphenylmethyIoxy- 3,5-phenylboranatohexanoate (Formula VI)
  • the crude product from example-3 was dissolved in 100ml of toluene and 5.6g of phenyl boronic acid was added. Water was removed by azeotropic distillation over a period of 3h.
  • the reaction mixture was cooled to RT and toluene was removed under reduced pressure. 30ml of methanol was added and the precipitated solid was filtered to give lOg of the title product.
  • Example 5 Synthesis of tert-butyl 6-hydroxy-3,5- (phenylboranato)hexanoate (Formula II)
  • Rl and R2 are alkyl 1 to 3 carbons
  • R3 is alkyl from 1 to 8 carbons
  • Rl and R2 are alkyl from 1 to 5 carbons

Abstract

La présente invention porte sur des dérivés de dihydroxy hexanoate optiquement actifs, sur des esters de boronate de formule (IIa) qui sont utiles comme intermédiaires dans la synthèse des inhibiteurs de l'enzyme HMG-CoA tels que l'atorvastatine, la cérivastatine, la rosuvastatine, la pitavastatine, la fluvastatine. Ar = aryle ou hétéroaryle non substitué ou substitué, R3 = alkyle contenant de 1 à 8 atomes de carbone, aryle ou aralkyle, R4 = O, OH, CN ou un halogène et a = une liaison unique ou une double liaison.
