Electric Literature of 38028-67-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst.

3-Alkyl-2-methoxypyrazines (MPs) are a very important class of volatile organic compounds (VOCs), intensively characterizing the aroma of several food products including fruits and vegetables. Due to the very low orthonasal sensory threshold, low amounts of MPs may act as key positive or negative aroma compounds. The analysis of these volatiles in foods is then remarkably important, and it may be very challenging as confirmed by the scarce literature focused on MPs, particularly with respect to quantitative data. In the attempt to fill this gap, in this work, presence and quantification of MPs in four different vegetables, namely, green bell pepper (Capsicum annuum L. var grossum), green pea (Pisum sativum L. and Pisum spp), carrot (Daucus carota subsp sativus), and cucumber (Cucumis sativus L.) have been investigated. Two different volatile extraction techniques (solid phase microextraction [SPME] and simultaneous distillation-extraction [SDE]) in conjunction with VOC qualitative analysis by gas chromatography-mass spectrometry (GC-MS) methods were applied. Solid phase microextraction coupled with GC-MS in single ion monitoring (SIM) mode showed the best performances in sensitivity to detect MPs on the different vegetable matrices. Therefore, a headspace (HS) SPME-GC-MS quantitative method was developed and optimized, and dominant MPs quantified. 3-Isopropyl-2-methoxypyrazine (IPMP), 3- sec-butyl-2-methoxypyrazine (sBMP), and 3-isobutyl-2-methoxypyrazine (IBMP) have been detected and quantified in all the vegetables. 3-Isopropyl-2-methoxypyrazine was the prevalent MP in peas and cucumber while IBMP in bell pepper. These MPs were detected for the first time in carrot and cucumber. Finally, sBMP has been confirmed to be the most important MP in carrot. The developed method allowed to characterize the VOC pattern and, in particular, to quantify MPs in four vegetables. Results highlight the feasibility of further applications of the analytical approach to determine MPs in other food matrices where an excessive amount of these aromas may negatively affect their flavor (eg, coffee).

G protein coupled receptor 119 (GPR119) is viewed as an attractive target for the treatment of type 2 diabetes and other elements of the metabolic syndrome. During a program toward discovering agonists of GPR119, we herein describe optimization of an initial lead compound, 2, into a development candidate, 42. A key challenge in this program of work was the insolubility of the lead compound. Small-molecule crystallography was utilized to understand the intermolecular interactions in the solid state and resulted in a switch from an aryl sulphone to a 3-cyanopyridyl motif. The compound was shown to be effective in wild-type but not knockout animals, confirming that the biological effects were due to GPR119 agonism.

Hydroxyallylpyridyl derivatives exhibited a peculiar thermal behavior likely ascribed to the weak acidity of the ‘picoline-type’ hydrogen atom on the C-1 carbon of the allyl residue, leading to allyl inversion products. The unprotected alcohol reacted as ‘vinylogous picoline’ carbon nucleophile with strongly activated heterocyclic counterparts. A mechanistic rationale for this unprecedented reactivity was proposed.
