Structure-Based Design of Potent, Selective, and Orally Bioavailable VPS34 Kinase Inhibitors
VPS34 is a class III phosphoinositide 3-kinase involved in endosomal trafficking and autophagosome formation. Inhibitors of VPS34 were believed to have value as anticancer agents, but genetic and pharmacological data suggest that sustained inhibition of V

Long-range diastereoselectivity in an Ugi reaction: Stereocontrolled and diversity-oriented synthesis of tetrahydrobenzoxazepines
Salicylaldehydes and protected 1,2-amino alcohols have been convergently converted into a series of 2,3-dihydrobenzo[f][1,4]oxazepines, which undergo an Ugi-Joullie multicomponent reaction with unusual long-range diastereoselectivity. This protocol allows
Asymmetric synthesis of α-alkylated aldehydes using terminal epoxide-derived chiral enamines
(Chemical Equation Presented) Effective discrimination: Efficient lithium amide-induced terminal epoxide-enamine transformation provides the first enamines capable of generating α-alkylated aldehydes with high asymmetric induction by intermolecular nucleophilic substitution (see scheme).

PRODUCTION OF OXY-MICHAEL ADDUCTS
The invention provides a method of producing an oxy-Michael adduct comprising allowing a Michael acceptor to react with an alkoxide of an alcohol of formula R0H having a chiral centre at the hydroxy carbon, in the presence of a multidentate ligand. The

Highly diastereoselective oxy-Michael additions of enantiopure δ-lactol anions to nitroalkenes: Asymmetric synthesis of 1,2-amino alcohols
The "naked" alkoxide 1 of (S)-6-methyl-δ-lactol acts as an excellent chiral hydroxide equivalent in highly diastereoselective oxy-Michael additions to nitroalkenes (see scheme). The excellent stereoinduction arises from what becomes a superb protecting gr

Diastereo- and enantioselective synthesis of vicinal amino alcohols by oxa Michael addition of N-formylnorephedrine to nitro alkenes
The first intermolecular asymmetric oxa Michael additions with removable chirality information within the hydroxide source are reported. As enantiopure oxygen nucleophile functioning as chiral hydroxide equivalent N-formylnorephedrine (7) was used and conjugate additions to aliphatic (E)-nitro alkenes 2a-j were carned out in good yields (35-87%) and excellent diastereomeric excesses (de = 94-≥98%). After reduction of the nitro group and protection of the amino function (11a-h, 73-87%, both steps), the cleavage of the auxiliary occurred without epimerisation (69-99%) using Na/NH3. The Boc-protected 2-amino alcohols 12a-h could be obtained in good overall yields (30-58 %, four steps) and excellent diastereomeric and enantiomeric excesses (de, ee = 94-≥98%). Transition states explaining the overall stereochemical outcome are presented based on the absolute configuration determined by X-ray structure analysis on 8b.
