Expedient synthesis of novel beta-ketoesters from the Mizoroki-Heck coupling of ethyl 3-ethoxyacrylate with aryl and pyridyl halides

It is well known that beta-ketoesters are useful intermediates for the synthesis of a range of heterocyclic templates. While there are many useful synthetic methods available to access these intermediates, there are still opportunities for the discovery of useful methodologies for their construction from novel starting materials. In this regard, we report on the discovery of a facile Pd-catalyzed Mizoroki-Heck coupling of ethyl 3-ethoxyacrylate with aryl and heteroaryl halides to form substituted alkoxyacrylates which can be hydrolyzed to form novel aryl and heteroaryl beta-ketoesters.

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.Computed Properties of C24H56Br2P2Pd2, you can also check out more blogs about185812-86-6

The palladium-catalyzed cross-coupling reaction of 9-organothio-9-borabicyclo[3.3.1]nonanes with organic electrophiles: Synthesis of unsymmetrical sulfides

The synthesis of unsymmetrical sulfides was carried out in high yields by the palladium-catalyzed cross-coupling reaction of 9-organothio-9-borabicyclo[3.3.1]nonane (9-RS-9-BBN) with organic electrophiles, such as iodoarenes, 1-iodo-1-alkenes, allyl carbonate and propargyl carbonate. Iodoarenes and 1-iodo-1-atkenes were smoothly converted into the corresponding sulfides at 50 C in the presence of PdC12(dppf) (3 mol%) and K3PO4 (3 equiv.) in DMF. In contrast, the cross-coupling reaction of 9-RS-9-BBN with allyl or propargyl carbonates occurred in DMF without the assistance of a base. Both reactions catalyzed by Pd(dba)2-dppf regioselectively produced allyl and allenyl sulfides in excellent yields. The scope and limitations of the reactions, as well as the effects of varying the reaction conditions, are discussed.

Synthesis of Electron-Deficient Heteroaromatic 1,3-Substituted Cyclobutyls via Zinc Insertion/Negishi Coupling Sequence under Batch and Automated Flow Conditions

Synthesis of 1,3-substituted cyclobutyls enabled by zinc insertion into functionalized iodocyclobutyl derivatives followed by Negishi coupling with halo-heteroaromatics is reported. Two distinct sets of conditions were developed; the first involved a two-step batch protocol using activated Rieke zinc, and the second involved a multistep continuous flow process. Both methods showed complementarity and allowed for rapid access to these medicinally relevant motifs, the possibility of scaling up, and automation for library synthesis.

Comparartive Study on the Reactivity of 6-Haloimidazo[1,2-a]pyridine Derivatives towards Negishi- and Stille-Coupling Reactions

The scope of the Suzuki-cross-coupling reaction of 6-haloimidazo[1,2-a]pyridines is dependent on the availability of the (hetero)arylboronic acids. Thus, with the aim to develop expanded applications of (hetero)arylations of imidazo[1,2-a]pyridines, we investigated the Negishi- and Stille-cross-coupling reactions at the 6-position. Remarkably, attempts to aply the Negishi-cross-coupling conditions to the organozinc derivative prepared from 6-haloimidazo[1,2-a]pyridine via a lithium-zinc exchange led to the 5-phenyl compound 3 in 54 percent yield instead of the desired 6-phenyl-isomer (Scheme 1). In contrast, various commercially available halogenated five- or six-membered-ring heterocycles were efficiently coupled to the 6-(trialkylstannyl)imidazo[1,2-a]pyridine under Stille conditions (Table 2).

In vitro assessment of cytotoxicity, anti-inflammatory, antifungal properties and crystal structures of metallacyclic palladium(II) complexes

Metallacyclic palladium(II) complexes [Pd(L)(R3P)Cl], L = TIQDTC (1,2,3,4-tetrahydroisoquinolinedithiocarbamate), 4MpipDTC (4-methylpipradinedithiocarbamate), MPizDTC (N-methylpiperazinedithiocarbamate), R3P = Ph3P, (o-tolyl)3P, Ph2ClP, were synthesized in a 1:1 molar metal-ligand ratio. These complexes were characterized by elemental analyses, FT-IR, multinuclear (1H, 13C and 31P) NMR. The X-ray crystal structures of [Pd(TIQDTC)(Ph3P)Cl] and [Pd(TIQDTC)((o-tolyl)3P)Cl] show a slightly distorted square planar environment around the Pd(II) ion with S-Pd-S and P-Pd-Cl average bond angles of 74.51 and 92.41, respectively. These complexes were screened for cytotoxic, antifungal, anti-inflammatory and antibacterial activity. Some complexes exhibit a significant activity against fungi.
