Palladium-Catalyzed C-2 C-H Heteroarylation of Chiral Oxazolines: Diverse Synthesis of Chiral Oxazoline Ligands was written by Xi, Tuo; Mei, Yuncai; Lu, Zhan. And the article was included in Organic Letters on December 18,2015.Formula: C16H15NO2 The following contents are mentioned in the article:

A direct, efficient, and practical protocol to install a chiral oxazoline unit onto aryl/heteroaryl rings via palladium-catalyzed C-H functionalization of 2-positions of oxazolines with a variety of halides using dppe as the ligand has been developed. Various chiral oxazoline ligands could be synthesized, even in a 10-g scale process. This protocol is a good supplement to traditional methods and for diverse synthesis of chiral oxazoline ligands. This study involved multiple reactions and reactants, such as (S)-2-(4-Benzyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-92-2Formula: C16H15NO2).

(S)-2-(4-Benzyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-92-2) belongs to oxazolidine derivatives. Oxazolidine-based compounds have started to attract attention also in the medicinal and materials chemistry fields. In another report, the incorporation of an additional substituted oxazolidine ring over a range of new biphenylazepinium salt organocatalysts for the asymmetric epoxidation of alkenes improved enantiocontrol over the parent structures.Formula: C16H15NO2

Reactions of m-chloroperoxybenzoic acid with dimeric cyclopalladated complexes derived from 2-phenyl-2-oxazolines was written by Kukowski, Jonathan E.; Keuseman, Kristopher J.; Smoliakova, Irina P.. And the article was included in Transition Metal Chemistry (Dordrecht, Netherlands) on November 30,2015.Synthetic Route of C13H17NO2 The following contents are mentioned in the article:

Cyclopalladated complexes (CPCs) (S,S)-di-μ-Cl(κ2-C,N)2Pd2 (1a,b) and (S,S)-di-μ-OAc(κ2-C,N)2Pd2 (7a,b) obtained from (S)-4-t-butyl-(a) and (S)-4-ethyl-2-phenyl-2-oxazoline (b) were reacted with m-chloroperoxybenzoic acid (m-CPBA) at room temperature in methylene chloride, Et acetate or acetonitrile followed by workup with lithium chloride. Oxidation products formed in these reactions include dinuclear complexes (S,S)-di-μ-Cl(κ2-N,O)2Pd2 (2a), (S,S)-di-μ-oxo(κ2-N,O)2Pd2Cl2 (2b), and (S,S)-di-μ-(m-Cl-C6H4CO2)(κ2-N,O)2Pd2 (3a,b), mononuclear derivatives (S,S)-bis(κ2-N,O)Pd (4a,b) and dinuclear monooxidn. complexes (S,S)-di-μ-Cl(κ2-N,O)(κ2-C,N)Pd2 (5a,b). Each complex was isolated in low yield (6-46 %) with the combined yield of oxidation products reaching up to 64%. The best selectivity in product distribution was observed for the reactions of μ-OAc-CPCs 7a,b with 2.7 equiv of m-CPBA in acetonitrile, in which oxygen-insertion adducts 2a and 4b were isolated in 44 and 46% yields, resp. The structures of all complexes were supported by spectroscopic methods. An x-ray crystallog. study of compound 4a was performed, confirming its mononuclear structure and revealing an unusual bent geometry. This study involved multiple reactions and reactants, such as (S)-2-(4-(tert-Butyl)-4,5-dihydrooxazol-2-yl)phenol (cas: 135948-04-8Synthetic Route of C13H17NO2).

(S)-2-(4-(tert-Butyl)-4,5-dihydrooxazol-2-yl)phenol (cas: 135948-04-8) belongs to oxazolidine derivatives. Oxazolidines that are the precursor to bisoxazolidines are in effect mono-oxazolidines. They are also used as moisture scavengers in polyurethane and other systems. Oxazolidines are commonly used as metal ligands in asymmetric catalysis, synthetic intermediates in organic synthesis, and also used as the protecting groups.Synthetic Route of C13H17NO2

Enantioselective Cu-catalyzed 1,4-addition of Me3Al to a 4,4-disubstituted cyclohexa-2,5-dienone was written by Takemoto, Yoshiji; Kuraoka, Satoru; Hamaue, Naoko; Aoe, Keiichi; Hiramatsu, Hajime; Iwata, Chuzo. And the article was included in Tetrahedron on November 4,1996.Computed Properties of C13H17NO2 The following contents are mentioned in the article:

A series of chiral enantiomerically pure 2-aryloxazolines was synthesized. (4S)-2-(2′,6′-dimethoxyphenyl)-4-isopropyloxazoline proved to be an efficient chiral ligand for the Cu-catalyzed conjugate addition of Me3Al to cyclohexadienone, and by using 20 mol% of this ligand, 1,4-adduct was obtained in 68% ee. In addition, TBDMSOTf is crucial for the asym. conjugate addition to proceed with good chem. yield and high ee.
