Stereoselective synthesis of spirooxindoles by palladium-catalyzed decarboxylative cyclization of gamma-methylidene-beta-valerolactones with isatins

Image Presented A new synthetic method of spirooxindole derivatives has been developed by way of a palladium-catalyzed decarboxylative cyclization of gamma-methylidene-beta-valerolactones with isatins. By employing a newly prepared phosphoramidite ligand, the reaction proceeds smoothly with excellent diastereoselectivity. Preliminary results of its application to asymmetric catalysis using a chiral phosphoramidite ligand are also described.

2,2?-biphenols via protecting group-free thermal or microwave-accelerated suzuki-miyaura coupling in water

User-friendly protocols for the protecting group-free synthesis of 2,2?-biphenols via Suzuki-Miyaura coupling of o-halophenols and o-boronophenol are presented. The reactions proceed in water in the presence of simple additives such as K2CO3, KOH, KF, or TBAF and with commercially available Pd/C as precatalyst. Expensive or laboriously synthesized ligands or other additives are not required. In the case of bromophenols, efficient rate acceleration and short reaction times were accomplished by microwave irradiation.

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.HPLC of Formula: C12H10O2, you can also check out more blogs about1806-29-7

A convenient synthesis of (Z)-3-(alpha-Cyano-alpha-alkoxy-carbonylmethylene)- 2-piperazinones and their derivatives

(Z)-3-(alpha-Cyano-alpha-alkoxycarbonylmethylene)-2-piperazinone derivatives (3) and trans-(Z)-3-(alpha-cyano-alpha-alkoxycarbonylmethylene)octahydro-2(1H)- quinoxalinone derivatives (5) possessing various alkoxycarbonyl groups are prepared directly from the reaction of dialkyl (E)-2,3-dicyanobutenedioates (1) with ethylenediamine (2) and with trans-1,2-diaminocyclohexane (4), respectively. Furthermore, cis-1,2-diaminocycloheptane (6) and meso-2,3- diaminobutane (8) were reacted with the diethyl ester 1b to give cis-(Z)-3- (alpha-cyano-alpha-ethoxycarbonylmethylene)decahydro-2H-cycloheptapyrazin-2-one (7) and cis-(Z)-3-(alpha-cyano-alpha-ethoxycarbonylmethylene)-5,6-dimethyl-2- piperazinone (9), respectively. The structural studies of 3, 5, 7, and 9 were carried out by NMR experiments in some details.

Cytotoxic neolignans: An SAR study

The cytotoxic effects of different neolignans with the structure 1 were studied. The neolignans, magnolol 1 and honokiol 2 have been reported to inhibit the growth of several tumor cell lines in vitro and in vivo. The chemical structure of magnolol and honokiol consists of biphenyl skeleton with phenolic and allylic functionalities. Analogs of 1 and 2 containing different substitution have been studies for their effect on the growth of Hep-G2 and their structure-activity relationships were reported in this work.

Synthesis and biological studies of novel 2-aminoalkylethers as potential antiarrhythmic agents for the conversion of atrial fibrillation

A series of 2-aminoalkylethers prepared as potential antiarrhythmic agents is described. The present compounds are mixed sodium and potassium ion channel blockers and exhibit antiarrhythmic activity in a rat model of ischemia-induced arrhythmias. Structure-activity studies led to the identification of three compounds 5, 18, and 26, which were selected based on their particular in vivo electrophysiological properties, for studies in two canine atrial fibrillation (AF) models. The three compounds converted AF in both models, but only compound 26 was shown to be orally bioavailable. Resolution of the racemate 26 into its corresponding enantiomers 40 and 41 and subsequent biological testing of these enantiomers led to the selection of (1S,2S)-1-(1-naphthalenethoxy)-2-(3- ketopyrrolidinyl)cyclohexane monohydrochloride (41) as a potential atrial selective antiarrhythmic candidate for further development.

Molecular self-assembly and optical activity of chiral thionooxalamic acid esters

Three chiral bisthionooxalamides were synthesized by acylation with ethyl or (1R)-menthyl chloroxoacetate of the corresponding diamines and subsequent thionation with Lawesson’s reagent. Single crystal X-ray diffraction analysis revealed that products 4b-7b self-assemble in the solid state by the ring [N-H…O{double bond, long}C, R22 (10)] or chain [N-H…S{double bond, long}C, C(4)] hydrogen-bond motifs. Only in the case of 4b was a helical superstructure formed. In racemic compound 6b, the molecules are connected via N-H…S{double bond, long}C hydrogen bonds into homochiral chains, similar to those formed in 7b. The solid state CD spectra of chiral bisthionooxalamides are characterized by strong Cotton effects in the region of the thioamide n-pi* transition. Their sign is determined by the helicity of the S{double bond, long}C-C{double bond, long}O unit.

Spectroscopic studies of Schiff bases of 2,2?-dihydroxybiphenyl-3-carbaldehyde and para substituted anilines

Five Schiff bases derivatives of 2,2?-dihydroxybiphenyl-3-carboxaldehyde and various para substituted anilines have been synthesised and studied by FT-IR, 1H, 13C, 15N NMR and CPMAS spectroscopy. The structure of the Schiff base includes two intramolecular OH?O and OH?N hydrogen bonds forming a hydrogen-bonded chain. All Schiff bases studied exist in imine form in chloroform and acetonitrile solution. On the basis of the CPMAS and FT-IR spectra in solid state the SCH5 base has been proved to exist in the enamine form. ? 2003 Elsevier Science B.V. All rights reserved.
