Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 78502-81-5, Name is 5-Bromo-2-methyl-4-phenylthiazole. In a document type is Article, introducing its new discovery., 78502-81-5

Bromination of methylthiazoles with one unsubstituted position by N-bromosuccinimide may take place either at the methyl group, at the heterocyclic nucleus, or at both positions according to the nature of the second substituent.The ethoxycarbonyl group in the compounds 1a-3a directs the bromine into the side chain.So it is possible to obtain the tribromomethyl compounds 1d and 2d without bromination of the thiazole nucleus.In the phenyl-substituted methylthiazoles 4a-6a bromination takes place in the methyl group and in the heterocyclic nucleus. – The bromomethylthiazoles 1b-3b yield the vinylthiazoles 1k-3k by Wittig reaction.

The efficient synthesis of 2-substituted thiazoles and benzothiazoles has been accomplished employing readily available cysteine esters and 2-aminobenzenethiols as N and S sources. The reaction proceeds under an I2/TBHP system and involves a one-pot tandem cyclization and oxidation sequence. A diverse range of aldehydes is amenable for this transition-metal-free protocol, which provides an alternative method to rapidly access thiazole-containing molecules.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 18640-74-9, C7H11NS. A document type is Conference Paper, introducing its new discovery., 18640-74-9

An empirical model was developed to describe and predict the change in gas-liquid partition behaviour of a wide range of volatile compounds in aqueous sucrose solutions. The static equilibrium headspace concentrations of 40 volatiles (from different chemical classes e.g. pyrazines, alcohols, esters and ketones and with different physical properties e.g. volatility and solubility), were measured above aqueous sucrose solutions [0-65% (w/v)]. As sugar concentration increased, the headspace concentration of some compounds increased, whilst others stayed the same or decreased. The changes in volatile headspace concentrations were correlated (using partial least squares regression) with a range of physicochemical descriptors which were calculated from the compound structure. The model was composed of seven physicochemical descriptors and had a regression coefficient, R2=0.74. An external test set was used to validate the model. The key descriptors in the model were (log P)2, LUMO energy and a connectivity index term. Copyright (C) 2000 Elsevier Science Ltd.
