Hydrolysis of (2-deoxy-beta-D-glucopyranosyl)pyridinium salts

The hydrolysis reactions of three (2-deoxy-beta-D-glucopyranosyl)pyridinium salts exhibit first-order rate constants that are independent of pH in the range of 4.4-10.1 pH units. Derived second-order rate constants for the hydrolysis reactions of (2-deoxy-beta-D-glucopyranosyl)-4?-bromoisoquinolinium bromide (5b) conducted in the presence of nucleophilic monoanions (mu = 2.0) including AcO-, Cl-, Br-, and N3 exhibit a Swain-Scott parameter (s) of 0,03 ¡À 0.05, indicating that these reactions show no sensitivity to the nature of the anion. However, a substantial quantity of the (2-deoxyglucopyranosyl)pyridinium salt hydrolysis product is formed as a result of a post-rate-limiting reaction involving a nucleophilic anion. Analysis of the product ratios indicates that the first-formed intermediate in the hydrolytic reaction is a solvent-separated ion painmolecule encounter complex. The data allow a calculated estimate of greater than 2.5 ¡Á 10-12 s for the lifetime of the glucopyranosyloxocarbenium ion in aqueous solution.

Studies of (Pd0-mediated) stille cross-coupling reactions of thiophenestannane with aryl halide derivatives

Stille (arylstannane) conditions used Pd0-mediated cross-coupling reactions for preparation of thiophene/aryl analogs. Different arylhalides were compared when coupled with heterometal (thiophenestannane) system. Comparable yields have now been obtained by Stille (arylstannane) couplings with different reactivity of arylhalides.

Synthesis of (E)-1-aryl alk-1-en-3-ones by tetraphosphine/palladium- catalysed Heck reactions of alk-1-en-3-ones with aryl bromides

The tetraphosphine cis,cis,rediscovercis-1,2,3,4- tetrakis(diphenylphosphinomethyl)cyclopentane in combination with [Pd(C 3H5)Cl]2 affords a very efficient catalyst for the Heck reaction of alk-1-en-3-ones with aryl bromides. If appropriate reaction conditions are used (NaOAc as base, hydroquinone as stabilising agent and DMF as solvent) high yields of (E)-1-aryl alk-1-en-3-one derivatives are obtained. In general, higher reaction rates were observed with electron-poor aryl bromides, but the electron-rich aryl bromides 4-N,N-dimethylaminobromobenzene and 4-bromoanisole also led to the arylated enones. Even with sterically very congested aryl bromides such as 9-bromoanthracene, 2,4,6-trimethylbromobenzene or 2,4,6-triisopropylbromobenzene, the expected (E)-1-aryl alk-1-en-3-ones were obtained in moderate to good yields. Moreover, several reactions can be performed with as little as 0.1% catalyst. Georg Thieme Verlag Stuttgart.

Sonogashira reaction of heteroaryl halides with alkynes catalysed by a palladium-tetraphosphine complex

cis,cis,cis-1,2,3,4-Tetrakis(diphenylphosphinomethyl)cyclopentane/(1/2)[PdCl(C3H5)]2 system catalyses the Sonogashira reaction of heteroaryl halides with a range of alkynes with moderate to high substrate/catalyst ratios in good yields. A variety of heteroaryl halides such as pyridines, quinolines, a pyrimidine, an indole, thiophenes, or a thiazole have been used successfully. The reaction also tolerates several alkynes such as phenylacetylene and alk-1-ynols. The nature of the heteroaromatics and the substituent of the alkynes have both an important effect on the reaction rates. High reaction rates were generally observed with phenylacetylene. With this alkyne substrate/catalyst ratios up to 10,000 have been used successfully. An effect of the position of the alcohol function on the reaction rates was observed with alk-1-ynols. Higher substrate/catalyst ratios could be used with but-3-yn-1-ol, pent-4-yn-1-ol or hex-5-yn-1-ol than with propargyl alcohol. The nature and the position of the halide on the heteroaromatics have also an important effect on the reaction rates. As expected, higher reaction rates were obtained with heteroaryl iodides than with heteroaryl bromides or chlorides.

Let it flow: An efficient and modular synthesis of biaryls under continuous-flow conditions has been realized by a lithiation/borylation/Suzuki- Miyaura cross-coupling sequence under ambient conditions. Aryl bromides and heteroaromatic precursors can be transformed in the room-temperature lithiation reaction with nBuLi, followed by borylation and Suzuki-Miyaura coupling with the aid of ultrasonic irradiation (see scheme).

Novel azalides derived from 16-membered macrolides. Part II: Isolation of the linear 9-formylcarboxylic acid and its sequential macrocyclization with an amino alcohol or an azidoamine

The design and synthesis of novel 14- to 16-membered 11-azalides starting from 16-membered macrolides are reported. A linear 9-formylcarboxylic acid was isolated via a mobile dialdehyde previously reported. Sequential macrocyclization of the formylcarboxylic acid with amino alcohol followed by deprotection afforded corresponding 14- to 16-membered azalides. On the other hand, reductive amination of the formylcarboxylic acid with an azidoamine followed by macrolactam formation with an amine generated from the azide gave 14- to 16-membered azalactams. Among these derivatives, 15-membered azalactams and 16-membered azalides exhibited characteristic in vitro antibacterial activities. Although optimization of 15-membered azalactams including demycarosyl analogues did not provide remarkably promising molecules, SAR studies of 16-membered azalides disclosed that substitution at the 15 position was very important for identification of a clinical candidate.
