Abstract
A synthesis of dihydropyrazino-[2,1-b]-quinazolinones is described using a 2-alkylaminoquinazolinone-mediated ring opening of a-/chiral sulfamidates, followed by a tandem quinazolinone-amidine rearrangement termed SQuAReS. This approach takes advantage of sulfamidates whose regioselective ring opening, after hydrolysis, appends an optimally distanced nucleophilic amine to a quinazolinone such that subsequent domino rearrangements are favored, integrating unique substitution patterns on a privileged core. This three-step protocol integrated five telescoped transformations and generated 20 pyrazinoquinazolinones in up to 74% yield with high enantiomeric fidelity and diastereoselectivity.

Abstract
Chiral amines are among the most important organic compounds and have widespread applications. Enantioselective construction of chiral amines is a major aim in organic synthesis. Among synthetic methods, direct functionalization of omnipresent C-H bonds with common organic nitrogen compounds represents one of the most attractive strategies. However, C-H amination strategies are largely limited to constructing a specific type of N-heterocycles or amine derivatives. To maximize the synthetic potential of asymmetric C-H amination, we report here an approach that unites the complementary reactivities of radical and ionic chemistry for streamlined synthesis of functionalized chiral amines. This synthesis merges the development of an enantioselective radical process for 1,5-C(sp 3)-H amination of alkoxysulfonyl azides via Co(II)-based metalloradical catalysis with an enantiospecific ionic process for ring-opening of the resulting five-membered chiral sulfamidates by nucleophiles. Given that alkoxysulfonyl azides are derived from the corresponding alcohols, this approach offers a powerful synthetic tool for enantioselective β-C-H amination of common alcohols while converting the hydroxy group to other functionalities through formal nucleophilic substitution.

Abstract
Highly selective mTOR inhibitors have been discovered through the exploration of the heteroaromatic ring engaging the binding affinity region in mTOR kinase. Compound 11 showed predicted BBB permeability in a MDCK-MDR1 permeability in vitro assay, being the first pyrimido-pyrrolo-oxazine with potential application in the treatment of neurological disorders. Here we present the first pyrimido-pyrrolo-oxazine-based mTOR kinase inhibitor (11) predicted to penetrate the blood brain barrier (BBB). Thus, 11 has a potential in treatments of neurological disorders.![]()

Abstract
The mechanistic target of rapamycin (mTOR) plays a pivotal role in growth and tumor progression and is an attractive target for cancer treatment. ATP-competitive mTOR kinase inhibitors (TORKi) have the potential to overcome limitations of rapamycin derivatives in a wide range of malignancies. Herein, we exploit a conformational restriction approach to explore a novel chemical space for the generation of TORKi. Structure-activity relationship (SAR) studies led to the identification of compound 12b with a ∼450-fold selectivity for mTOR over class I PI3K isoforms. Pharmacokinetic studies in male Sprague Dawley rats highlighted a good exposure after oral dosing and a minimum brain penetration. CYP450 reactive phenotyping pointed out the high metabolic stability of 12b. These results identify the tricyclic pyrimido-pyrrolo-oxazine moiety as a novel scaffold for the development of highly selective mTOR inhibitors for cancer treatment.
