A novel synthesis of the renin inhibitor aliskiren based on an unprecedented disconnection between C5 and C6 was developed, in which the C5 carbon acts as a nucleophile and the amino group is introduced by a Curtius rearrangement, which follows a simultaneous stereocontrolled generation of the C4 and C5 stereogenic centers by an asymmetric hydrogenation. Operational simplicity, step economy, and a good overall yield makes this synthesis amenable to manufacture on scale.

, (2013/08/28)
The present invention relates to an improved process for the preparation of compound of Formula-II, which is an intermediate in the preparation of Aliskiren and further conversion of compound of Formula-II into Aliskiren or its pharmaceutically acceptable salts. Formula-II wherein Ri and R2 are independently of one another H, Ci-C6 alkyl, C- C6 halogenalkyl, C]-C6 alkoxy, Ci-C6 alkoxy-Ci-C6 alkyl, or Ci-C6 alkoxy-Ci- C6 alkyloxy and X is halogen selected from fluoro, chloro, bromo and iodo
