(S)-5-Benzoyloxymethyl-3-[(E)-(dimethylamino)methylidene]tetrahydrofuran-2- one (6), prepared in 5 steps from L-glutamic acid (1), was used as precursor in a one step ‘ring switching’ synthesis of (S)-2-hydroxy-3-heteroaryl-1-propyl benzoates 13-18, 23, 24. In the reaction of 6 with 2-aminopyridine (21) and 2-amino-4,6-dimethylpyrimidine (22) the corresponding dimethylamine substitution products (25, 26) were obtained.

Herein, we report the nor-AZADO-catalyzed exhaustive aerobic oxidations of 1,2-diols to alpha-keto acids. Combining oxidation with transamination using dl-2-phenylglycine led to the synthesis of free alpha-amino acids (AAs) in one pot. This method enables the rapid and flexible preparation of a variety of valuable unnatural AAs, such as fluorescent AAs, photoactivatable AAs, and other functional AAs for bioorthogonal reactions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of (S)-( )-5-Oxo-2-tetrahydrofurancarboxylic Acid, you can also check out more blogs about21461-84-7

L-glutamic acid (1) was employed as a chiral template in the preparation of the pentachlorophenyl ester of (4S)-carboxy-1,4-butirolactone (3), a key precursor of chiral analogs of nylon 5,5 and nylon 5,6. Stereocontrol in the synthesis of these polymers was achieved by chemoselective condensation of the ester group of 3 with aminoalcohols. The alcohol function of the resulting N-(hydroxyalkyl)amides (4 and 9) was converted into amine by tosylation, azide substitution and hydrogenolysis. The amino lactones 7 and 12 thus obtained were conveniently functionalized for the polycondensation, which led to the stereoregular, crystalline polyamides 8 and 13.

Starting from (-)-acetoxyglutarimide, the enantioselective multistep synthesis of (-)-desethyleburnamonine, (-)-vindeburnol and (-)-3-epitacamonine has been demonstrated via a common hydroxyl-lactam intermediate with very good overall yields. The acetoxy function from (-)-acetoxyglutarimide was initially used as a handle to induce enantioselectivity and then as a latent source of the ketone carbonyl group. Most importantly, substrate dependent reversal of the diastereoselectivity in ester aldol reactions of hexahydroindolo[2,3-a]quinolizinones has been reported.

Three water-soluble silver(i) complexes, i.e., {[Ag(S-othf)]2} l, {[Ag(R-othf)]2} 2 and {[Ag2(R-othf)(S-othf)]} 3 (S- and R-Hothf = (£)-(+)- and (R)-(-)-5-oxo-2-tetrahydrofurancarboxylic acid, respectively), showing effective antibacterial and antifungal activities, have been synthesized and their crystal structures determined. Single-crystal X-ray analysis revealed that 1 and 2 in the solid state are a left- and a right-handed chiral helical polymer, respectively, formed by self-assembly of non-centrosymmetric, bis-carboxylato-bridged bis(carboxylato-O, O’)disilver dimers (Ag-Ag distances 2.822(1) A for 1 and 2.823(2) Afor 2; O-Ag-O angles 164.0(2), 155.2(2) for 1 and 163.8(3), 154.5(3) for 2). The helicity of 1 and 2 in the solid state is accomplished with a connection of one oxo group in one dimeric core to one of the silver(i) centers of the adjacent dimeric unit and also with simultaneous connection of one of the carboxylato oxygens to the silver(i) center of a different dimer. These bonding modes are quite different from those of the stair-like polymer 3 formed by self-assembly of the dimeric core (Ag-Ag 2.781(1) A; O-Ag-O angle 164.8(1)). Crystals of 3 with achiral polymer structure were identical with those of 4 obtained from an aqueous solution containing equal amounts of 1 and 2, evidencing the presence of a ligand replacement between 1 and 2 in aqueous solution. The complexes 1-3 have also been characterized by elemental analysis, TG/DTA, FT-IR, and ‘H and UC NMR spectroscopies. The wide spectra of effective antibacterial and antifungal activities observed in 1-3 suggested that the weaker silver(i)-O bonding properties play a key role in the antimicrobial activities.
