The present invention provides heterocyclic compounds, the stereoisomer thereof, the enantiomer thereof, or the pharmaceutically acceptable salt, which are capable of modulating the activity of Mer receptor tyrosine kinase (MERTK). This invention also provides pharmaceutical compositions thereof, methods to prepare the said compounds, and the use of such compounds as a medicament. The present invention is directed to MERTK inhibitory compounds with marked potency, thereby having an outstanding potential for a pharmaceutical intervention of cancer and any other diseases related to MERTK dysregulation.
7a-f can be diastereoselectively alkylated, using O-protected amino-alcohols as chiral inducers, to furnish alpha-substituted beta-amidophosphine boranes 8a-f and 9-12 with up to 72% diastereoisomeric excess. Selective deprotection afforded optically pure carboxylic derivative 13 which is a key intermediate for the synthesis of various potential chiral ligands for asymmetriccatalysis.
We have investigated two simple diastereoselective syntheses of substituted β-amidophosphonates. The first one involved a Michael addition to α,β-unsaturated amides 6 and 8a−d, derived fromchiral amino alcohols, and permitted the preparation of alkyl-substituted derivatives 7 and 9a−d with high diastereoselectivities (up to 95%) with the aid of a 1,5-asymmetric induction. The second one, involving

Treatment of the readily available (S)-(+) and (R)-(-)-2-aminobutan-1-ol 1 with sodium hydride followed by benzyl chloride, or a substituted benzyl halide, afforded the corresponding -benzyl bases 2-5 in high yields. These new bases are recommended for the large scale resolution of racemic acids. For instance, they proved efficient for the practical resolution of -acetylphenylglycine (±)-7, -acety
