A photoredox-catalzyed trifluoromethylation of enecarbamates process is reported. This pathway uses Togni’s reagent as the CF3 source and follows a radical/cationic pathway. Under the optimized conditions using [Ru(bpy)3(PF6)2] as the photocatalyst, a wide range of substituted enecarbamates can readily be difunctionalized by means of various O, N, and C nucleophiles.

This work describes the first examples of diastereoselective intramolecular cyclopropanations of a de novo class of push-pull carbenes derived from DMDO-epoxidations of chiral ynamides. This reaction sequence essentially constitutes a tandem epoxidation-cyclopropanation that effectively gives rise to a series of structurally unique amido-cyclopropanes. A plausible mechanistic model is proposed revealing insights into this novel cyclopropanation process.

Reference of 108149-65-1, Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments.

Syntheses of the calicheamicin amino sugar 6 and its erythro diastereomer 7 have been completed by a sequence involving the asymmetric allylboration of N-Boc-serinal acetonide L-8 with the tartrate ester modified allylboronates (R,R)-9 and (S,S)-9, respectively. The reaction of (R,R)-9 and L-8 in toluene provides 14 with 89:11 selectivity, whereas the reaction of (S,S)-9 with L-8 in Et2O provides the diastereomer 15 with 90:10 selectivity. It is shown that the relatively modest diastereoselectivity of these double asymmetric reactions is compromised by the low enantiomeric purity of 8 (86-87% ee), and data are provided indicating that these reactions should be highly diastereoselective (?95:5 in each case) if performed with enantiomerically pure aldehyde. The two diastereomeric homoallylic alcohols, 14 and 15, are easily elaborated into the targeted amino sugars 6 and 7 via the acetamide-substituted pyranosides 22 and 26. Methyl pyranosides 22a and 22e were shown to adopt preferentially the unexpected conformations B and D, with axial acetamide substituents, in nonpolar solvents, while the expected conformations A and C were strongly favored in d6-DMSO because of hydrogen bonding interactions with the solvent. The syntheses of 6 and 7 reported herein are expected to facilitate the design and synthesis of analogs of the calicheamicin aryl tetrasaccharide 3, which should prove useful in further analysis and applications of oligosaccharides as DNA binders.

You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.Related Products of 95715-86-9, Name is Methyl (R)-N-Boc-2,2-dimethyloxazolidine-4-carboxylate, molecular formula is C12H21NO5, introducing its new discovery.

Unsaturation was introduced at Delta4,6 and Delta6 of the sphingoid chain of naturally occurring ceramide 1 via a beta-keto sulfoxide (12) and sulfone (18) derived from N-Boc-L-serine methyl ester acetonide (9), affording two novel ceramide analogues, (2S,3R)-2-octanoylamidooctadeca-(4E,6E)-diene-1,3diol (2) and (2S,3R)-2-octanoylamidooctadec-(6E)-ene-1,3-diol (3). After C-alkylation of 12 with (E)1-bromo-2-tetradecene (8), a trans double bond was installed by elimination of PhS(O)H, providing conjugated dienone oxazolidine 13. Reaction of 18 with 8, followed by desulfonation (Al(Hg)), afforded keto-oxazolidine 20, which bears a (E)-Delta6 double bond. The syntheses of analogues 2 and 3 from ketones 13 and 20, respectively, were completed by the following sequence of reactions: diastereoselective reduction (NaBH4/CeCl3 or DIBAL-H), hydrolysis of the oxazolidine ring, liberation of the amino group, and installation of the N-amide group.

With the aim of reducing molecular weight and adjusting log D value of BACE inhibitors to more favorable range for BBB penetration and better bioavailability, we synthesized and evaluated several series of P3 cap modified BACE inhibitors obtained via replacement of the P3 NHBoc moiety as seen in 3 with other polar functional groups such as amino, hydroxyl and fluorine. Several promising inhibitors emerging from this P3 cap SAR study (e.g., 15 and 19) demonstrated good enzyme inhibitory potencies (BACE-1 IC50 <50 nM) and whole cell activities (IC50 ?1 muM).
