Page/Page column 145, (2018/09/08)
Compounds having formula (I) (IX), and enantiomers, and diastereomers, stereoisomers, pharmaceutically acceptable salts and prodrugs thereof, are useful as kinase modulators, including RIPK1 modulation. All the variables are as defined herein: (I), (II), (III), (IV), (V), (VI), (VII), (VIII), (IX).

Piperazines are found widely in commercially-available compounds and bioactive molecules (including many drugs). However, in the vast majority of these molecules, the piperazine ring is isolated (i.e. not fused to another ring) and is not substituted on any of its carbon atoms. A modular synthetic approach is described in which combinations of cyclic sulfamidate and hydroxy sulfonamide building blocks may be converted into piperazines and related 1,4-diazepine and 1,5-diazocane scaffolds. By variation of the combinations of building blocks used, it was possible to vary the ring size, substitution and configuration of the resulting heterocyclic scaffolds. The approach was exemplified in the synthesis of a range of heterocyclic scaffolds that, on decoration, would target lead-like chemical space. It was demonstrated that lead-like small molecules based on these scaffolds would likely complement those found in large compound collections. This journal is the Partner Organisations 2014.

Enantioselective reduction of β-keto nitriles to optically active 1,3-amino alcohols has been carried out in one step using an excess of borane-dimethyl sulfide complex as a reductant and a polymer-supported chiral sulfonamide as a catalyst with moderate to high enantioselectivity. The facile and enantioselective method to prepare optically active 1,3-amino alcohols to be converted into 3-aryloxy-3-arylpropylamine-type antidepressant drugs (R)-fluoxetine, and (R)-duloxetine is also reported.
