Novel approach to stereoselective synthesis of (E)/(Z)-(N-acyl-oxazolidinone)-eneglycinates

(E)-(N-Acyl-oxazolidinone)-eneglycinates were synthesized with high stereoselectivity and in good yield by condensation of aldehydes with glycinates. (Z)-Eneglycinates could be prepared in high purity and moderate yield by transformation of (E)-eneglycinates under mild conditions. The effect on the (E)/(Z)-configuration of eneglycinates of steric hindrance by I¡À-substituents on the aldehyde was also examined. The software MMFF94 was used to explain the transformation of the thermodynamic product into the kinetic product and a plausible mechanism is given.

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.Recommanded Product: 184363-66-4, you can also check out more blogs about184363-66-4

Synthesis of novel 2,3,4-trisubstituted-oxazolidine derivatives and in Vitro cytotoxic evaluation

We have previously reported the discovery of cytotoxic and pro-Apoptotic hit compound 1,1-dimethylethyl (S)- 2,2-dimethyl-4-[(3-nitrophenoxy)methyl]-3- oxazolidinecarboxylate 1 against leukemia cells. In the present work we describe the synthesis of 25 derivatives of this hit varying the substituent at ring or stereochemistry of the oxazolidine ring and evaluated them against human cancer cells lines. Six compounds exerted significant activity against HL60 promyelocytic leukemia cells with IC50 in low micromolar range (4-18 muM) and three compounds displayed activity against MDA-MB231 breast cancer cells (25-37 muM). In vitro cytotoxicity on normal cells PBMC (human peripheral blood mononuclear cells) was also evaluated. Compounds 7e (p-NO2, S) and 7m (p-COOCH3, S) showed good antiproliferative activity against HL60 (4 and 5 muM) and MDA-MB231 (37 and 25 muM) without affecting lymphocyte proliferation in PBMC, indicating low toxicity to normal cells. Besides, compound 7e induced DNA fragmentation on about 100% of HL60 cells at 50 muM. In this case, it was more potent than 7m and lead 1. This indicated that compound 7e has a great pro-Apoptotic potential.

Synthesis of new C3 symmetric amino acid- and aminoalcohol-containing chiral stationary phases and application to HPLC enantioseparations

We recently reported a new C3-symmetric (R)-phenylglycinol N-1,3,5-benzenetricarboxylic acid-derived chiral high-performance liquid chromatography (HPLC) stationary phase (CSP 1) that demonstrated better results as compared to a previously described N-3,5-dintrobenzoyl (DNB) (R)-phenylglycinol-derived CSP. Over a decade ago, (S)-leucinol, (R)-phenylglycine, and (S)-leucine derivatives were used as the starting materials of 3,5-DNB-based Pirkle-type CSPs for chiral separation. In this study, three new C3-symmetric CSPs (CSP 2, 3, and 4) were prepared by combining the ideas and results mentioned above. Here we describe the synthetic procedures and applications of the new C3-symmetric CSPs (CSP 2?CSP 4).

Total Synthesis and Biological Evaluation of Siladenoserinol A and its Analogues

The total synthesis of siladenoserinol A, an inhibitor of the p53?Hdm2 interaction, has been achieved. AuCl3-catalyzed hydroalkoxylation of an alkynoate derivative smoothly and regioselectively proceeded to afford a bicycloketal in excellent yield. A glycerophosphocholine moiety was successfully introduced through the Horner?Wadsworth?Emmons reaction using an originally developed phosphonoacetate derivative. Finally, removal of the acid-labile protecting groups, followed by regioselective sulfamate formation of the serinol moiety afforded the desired siladenoserinol A, and benzoyl and desulfamated analogues were also successfully synthesized. Biological evaluation showed that the sulfamate is essential for biological activity, and modification of the acyl group on the bicycloketal can improve the inhibitory activity against the p53?Hdm2 interaction.
