Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 3194-15-8, is researched, SMILESS is O=C(C1=CC=CO1)CC, Molecular C7H8O2Journal, Monatsschrift fuer Brauwissenschaft called The use of oats in brewing, Author is Hanke, S.; Zarnkow, M.; Kreisz, S.; Back, W., the main research direction is oat beer brewing malting history.Related Products of 3194-15-8.

Oats (Avena sativa) are one of the most popular cereals for human consumption. In the middle ages oats were the brewing cereal par excellence. Over the centuries they were substituted by other cereals and their brewing properties were nearly forgotten. Today oats are popular once more because of their excellent health-related properties. For people who suffer with celiac disease oats are also of interest. Based on their historical use in brewing and their health-related properties pilot malting trials were carried out with different varieties, followed by brewing trials with a selected variety. The results obtained showed that oat malt is an appropriate choice for brewing.

The interaction of phospholipid in the Maillard reaction between cysteine and reducing sugars is of importance in the formation of meat flavor. The major volatile products of the aqueous reaction between cysteine and ribose, in the absence and presence of phospholipid, were studied by gas chromatog. (GC)-mass spectrometry and GC-IR spectroscopy, and the individual odors assessed by sensory evaluation of the GC effluent. Without phospholipid, S-containing heterocyclic Maillard products predominated, while the inclusion of phospholipid added lipid degradation products as well as certain compounds specific to the interaction of lipid in the Maillard reaction. The phospholipid also has a marked effect in the overall odor of the reaction mixtures and on the nature of the individual aromas detected.

A unified strategy to generate acyl radical from oxime ester via selective C-C bond activation is reported. Under visible-light irradiation, single-electron transfer from fac-Ir(ppy)3 to related oxime takes place followed by a fast β-fragment of C-C bond to yield aryl and aliphatic acyl radicals, subsequently captured by diverse Michael acceptors. More interestingly, the single-electron transfer enables coupling with energy transfer of the excited fac-Ir(ppy)3 via enone intermediate formed in situ for cyclobutane formation.
