Dynamic kinetic resolution of (S)-mandelate-derived a-bromo esters in nucleophilic substitution and asymmetric syntheses of 3-substituted morpholin-2-ones

Dynamic kinetic resolution of (S)-mandelate-derived α-bromo esters in nucleophilic substitution reaction has been investigated. Substitutions with various alkyl amine nucleophiles in the presence of TBAI and DIEA can provide various α-amino esters up to 81% yield and 97:3 dr. Also, the substitution of α-bromo esters with N-substituted 2-aminoethanol nucleophiles and following spontaneous cyclization provides a practical protocol for asymmetric syntheses of 3-substituted morpholin-2-ones up to 95:5 er.

Simple and efficient one pot synthetic protocol to construct morpholin-2-ones

A new one pot synthetic method to construct 3-substituted morpholine-2-one derivatives is presented. Amino acids refluxed with 1,2-dibromoethane and potassium carbonate in acetonitrile followed by treatment with benzyl bromide in same pot furnished the 3-

An asymmetric synthesis of 3-aryl-1,4-oxazin-2-ones: Synthesis of a key intermediate of an NK1 receptor antagonist

Pyrrolidine derived (S)-lactamide auxiliaries mediate a highly diastereoselective coupling reaction between racemic α-halo acids and N-benzylethanolamine. The adducts are readily cyclized upon treatment with a catalytic amount of TsOH giving the above tit

Stereoselective synthesis of 2-(S)-(3,5-bis(trifluoromethyl) benzyloxy)-3-(S)-phenyl-1,4-oxazine

A convenient process for the preparation of the secondary amine 6, 2-(S)-(3,5-bis(trifluoromethyl)benzyloxy)-3-(S)- (3,5-bis(trifluoromethyl)benzyloxy)-3-(S)-phenyl-1,4-oxazine, is described starting from the readily available (S)-phenylglycine 1. The process features efficient construction of the homochiral oxazinone intermediate 3 and stereoselective introduction of the 2-(3,5-bis(trifluoromethyl)-benzyloxy) group by L-Selectride reduction followed by in situ alkylation with the highly reactive 3,5-bis(trifluoromethyl)-benzyl triflate 4.
