Surface acoustic wave (SAW) technology has been featured in numerous publications for more than a decade because of the performance advantages and design flexibility. With the increasing of the frequency, the electrical effects become more important. The accurate prediction of the frequency response relies on a combination of good acoustic modeling techniques, rigorous die and package parasitic...
An efficient route to 5H-benzo[d]imidazo[5,1-b][1,3]thiazines has been developed using the copper(i)-catalyzed tandem reaction of o-alkynylphenyl isothiocyanates with isocyanides in THF with Cs2CO3 as base. The present tandem process allows the assembly of a variety of 5H-benzo[d]imidazo[5,1-b][1,3]thiazines in good to excellent yields.
Barley malt is critical for the malting, brewing, and distilling industries, as it one of main ingredients beer some types spirits. There growing evidence that barley genotype - via can impact flavors beers However, information on genes involved in these lacking. Therefore, we used quantitative trait locus (QTL) mapping quality traits, sensory descriptors metabolic compounds a biparental popula...
A short synthetic route to diastereoisomeric atropos dihydro-5H-dibenz[c,e]azepinium salts via reaction of a single enantiomer of (R)-α-methylbenzylamine with a racemic atropos biphenol derivative is described. Compounds prepared via this approach are used to provide strong evidence that structurally related tropos dihydro-5H-dibenz[c,e]azepinium salts preferentially react via a single conforma...
IN THE TITLE COMPOUND (SYSTEMATIC NAME 2-{4-[3-(5H-dibenz[b,f]azepin-5-yl)prop-yl]piperazin-1-yl}ethanol), C(23)H(29)N(3)O, the 5H-dibenz[b,f]azepine and piperazine rings adopt boat and chair conformations, respectively, and the overall shape of the fused ring part of the molecule is a butterfly. In the crystal, O-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a layer parallel to the bc ...
The effect of post-thaw incubation (0 vs. 5h at 15°C) and straw size (5 vs. 0.5ml) on motility, acrosomal integrity and in vitro fertilizing (IVF) capacity of cryopreserved boar spermatozoa was studied. In samples assessed immediately after thawing, no differences were found between the two straw sizes. After 5h post-thaw incubation, all parameters, except polyspermy, decreased and, spermatozoa...
A series of indolyl acrylamide derivatives was synthesized as potential diacylglycerol acyltransferase (DGAT) inhibitors. Furfurylamine containing indolyl acrylamide derivative 5h exhibited the most potent DGAT inhibitory activity using microsomes prepared from rat liver. Further evaluation against human DGAT-1 and DGAT-2 identified indolyl acrylamide analogues as selective inhibitors against h...
The influence of reaction conditions on the composition of liquid products during two-stage hydrothermal conversion of alkali lignin has been investigated in a batch reactor. Reactions were carried out in the presence of formic acid (FA) and Pt/Al2O3 catalyst. The two different sets of reaction conditions involved alternative reaction times of 1h and 5h at 265°C and 350°C, respectively. These p...
Sleep supports the formation of a variety of declarative and non-declarative memories, and sleep deprivation often impairs these types of memories. In human subjects, natural sleep either during a nap or overnight leads to long-lasting improvements in visuomotor and fine motor tasks, but rodent models recapitulating these findings have been scarce. Here we present evidence that 5h of acute slee...
The Lewis acid-catalyzed domino 1,2-addition/1,4-addition/elimination between (Z)-3-hexene-2,5-dione and 1,3-dicarbonyls delivers 3-methyl-6,7-dihydrobenzofuran-4(5H)-ones exclusively with yields up to 82%. The combination of this new process with the laccase-catalyzed formation of (Z)-3-hexene-2,5-dione by oxidative cleavage of 2,5-dimethylfuran allows for the synthesis of 6,7-dihydrobenzofura...
