A note on versions:The version presented here may differ from the published version or from the version of record. If you wish to cite this item you are advised to consult the publisher's version. Please see the repository url above for details on accessing the published version and note that access may require a subscription. We report a catalytic reductive alkylation reaction of primary or secondary amines with carboxylic acids. The two-phase process involves silane mediated direct amidation followed by catalytic reduction.
4-(Pyrimidin-4-yl)morpholines are
privileged pharmacophores for
PI3K and PIKKs inhibition by virtue of the morpholine oxygen, both
forming the key hydrogen bonding interaction and conveying selectivity
over the broader kinome. Key to the morpholine utility as a kinase
hinge binder is its ability to adopt a coplanar conformation with
an adjacent aromatic core favored by the morpholine nitrogen nonbonding
pair of electrons interacting with the electron deficient pyrimidine
π-system. Few selective morpholine replacements have been identified
to date. Herein we describe the discovery of a potent non-nitrogen
containing morpholine isostere with the ability to mimic this conformation
and its application in a potent selective dual inhibitor of mTORC1
and mTORC2 (29b).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
