The invention provides new processes for making and purifying amino acid compounds, which are useful in the preparation of AKT inhibitors used in the treatment of diseases such as cancer, including the compound (S)-2-(4-chlorophenyl)-1-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-(isopropylamino)propan-1-one.
The present invention relates to neurologically-active compounds, being heterocyclic compounds having two fused 6-membered rings with a nitrogen atom at position 1 and a hydroxy or mercapto group at position 8 with at least one ring being aromatic. Also disclosed are processes for the preparation of these compounds and their use as pharmaceutical or veterinary agents, in particular for the treatment of neurological conditions, more specifically neurodegenerative conditions such as Alzheimer's disease.

Due to the lability of one of the CO ligands in trans-[Fe(PNP)-(CO) 2 CI] + this compound is an efficient catalyst for the coupling of a series of aromatic aldehydes with ethyl diazoacetate (EDA), which give, in most cases, selectively 3-hydroxyacrylates rather than β-oxo esters. This reaction is strongly dependent on the nature of the counterion. Whereas with BF 4 - the reaction proceeds with conversions

An efficient method was developed to construct 2-pyridinones by the cycloaddition of nitro ketene aminal with 3-hydroxy-2-aryl-acrylate. The method uses readily-available starting materials and provided diverse bicyclic 2-pyridinones and multi-substituted 6-amino-2-pyridinones in good to excellent yields.
