One-pot synthesis of 5-alkylthio-3H-1,2-dithiole-3-thiones

Dialkyl malonate esters reacted with P2S5/S8 in boiling xylene and with 2-mercaptobenzothiazole/ZnO as catalyst to yield 5-alkylthio-3H-1,2-dithiole-3-thiones as major products.

Vapor pressures and enthalpies of vaporization of a series of the symmetric linear n -alkyl esters of dicarboxylic acids

Vapor pressures and the molar enthalpies of vaporization of the linear aliphatic alkyl esters of dicarboxylic acids R-CO2-(CH 2)n-CO2-R with n = (0 to 4) with R = C 2H5, n-C3H7, and n-C 4H9 have been determined using the transpiration method. A linear correlation of enthalpies of vaporization (at T = 298.15 K) of the esters with the number n and with Kovat's indices has been found, proving the internal consistency of measured data.

Efficient synthesis of dissymmetric malonic acid S, O -esters via monoalcoholysis of symmetric dithiomalonates under neutral conditions

A novel method for the highly selective synthesis of dissymmetric S,O-malonates starting from symmetric diphenyl dithiomalonates under neutral conditions is described. The key step is the thermal formation of an acylketene, the stability of which would co

Synthesis of caffeic acid esters

A new method for the preparation of caffeic acid esters was investigated. Ten caffeic acid esters were prepared by condensation of protocatechualdehyde with malonic acid mono-esters in moderate yield. Malonic acid mono-esters were prepared from the corresponding malonate di-esters. The conformations of compounds are trans (E) form.

One-Pot synthesis of 5-Alkylthio-3H-1,2-dithiole-3-thiones: Advantages and scopes

The reaction of dialkyl malonate esters with P2S5/S8 in boiling xylene in the presence of 2-mercaptobenzothiazole/ZnO as catalyst produces 5-alkylthio-3H-1,2-dithiole-3-thiones as major identifiable product. Moderate yields were obtained with malonate esters of primary alcohols. The reaction fails with malonate esters of secondary alcohols. Regarding the substituent in position two, dialkyl malonates with groups such as CH3, Ph, CH2Ph, OCH3 and Cl afford the corresponding 4-substituted derivatives whereas with Br and NO2 do not give the expected products. Some mechanistic evidences are described.

L-O-(2-malonyl)tyrosine (L-OMT) a new phosphotyrosyl mimic suitably protected for solidphase synthesis of signal transduction inhibitory peptides

A new phosphotyrosyl (pTyr) mimic L-O-(2-malonyl)tyrosine (L-OMT, 4) utilizes a malonyl structure in place of the parent phosphate group. This compound is stable to protein-tyrosine phosphatases and has advantages over phosphonate-based pTyr mimics in that protection of the malonyl group as its diester allows passage of the OMT across cell membranes, with subsequent esterase-mediated liberation of the free diacid once inside cells. Herein is reported the synthesis of Nα-Fmoc-L-OMT-O,O-(ferf-butyl)2 (5) for the solid-phase synthesis of L-OMT containing peptides as modulators of cellular signal transduction. Additionally included is the preparation of Nα-Fmoc-L-OMT-O,O-(n-butyl)2 (6) for the direct solid-phase synthesis of OMT-peptide diester prodrugs for use in cell-based studies.

SELECTIVE MONOETHERIFICATION AND MONOESTERIFICATION OF DIOLS AND DIACIDS UNDER PHASE-TRANSFER CONDITIONS

Research on the selectivity of etherification reactions of diols and esterification reactions of diacids by alkyl halides under phase-transfer catalysis has shown that under such conditions, selectivity of monoetherification increases in the order prim sec tert diols, though overall yield of monoether decreases from sec to tert diols.Monoesterification of diacids was accomplished with a high degree of selectivity.Optimal extraction of diols and diacids was found to correspond in general to chain lengths of around 5 carbons.This could mean that the complex formed between the catalyst and the anion to react is stabilized for certain carbon lengths by inner solvation in virtue of its spatial conformation.
