4-N-Alkoxycarbonylamino-2,6-dichloro- and -2-chloro-pyrimidines have been synthesized in good to excellent regioselectivity and yields from N-sodium carbamates and, respectively, 2,4,6-trichloropyrimidine and 2,4-dichloropyrimidine, in DMF, rt, 15-30 min. The reaction is effective also with 4,6-dichloropyrimidine, producing 4-N-alkoxycarbonylamino-6-chloropyrimidines in good yields. Some conformational features of 4-N-alkoxycarbonylamino-2,6-dichloro-pyrimidines have been investigated by X-ray diffraction and 1H NMR spectroscopy.

Synthetic Route of 497-25-6. Introducing a new discovery about 497-25-6, Name is Oxazolidin-2-one

Syntactic foams based on oxazolidone-modified epoxy resin using glass microballoons as reinforcing filler with varying densities were processed. The influence of various grades of microballoons and their concentration on the mechanical, thermal, thermomechanical, and flammability characteristics were investigated. The effect of temperature on the compressive strength with density was monitored in detail. By incorporating the microballoons, Tg of the syntactic foam increased from 90 C to 115 C. Thermal conductivity was found to decrease from (0.064 to 0.056 W/(m·K)) in conjunction with decreasing resin to filler ratio. In the case of composites filled with K25 alone, the creation of large voids due to less effective packing between the microballoons led to lower thermal conductivity. The specific heat of the different composites was in the range of 0.32 to 0.44 cal/g/C, and the coefficient of thermal expansion was in the range of 13.2 to 17.4 × 10?6/C with limiting oxygen index of 28% to 33%.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 497-25-6

A stereoselective synthesis of the anti-ulcer compound AI-77-B 1 is described. The 4-formylazetidinone 6 was converted into the 4-(Z)-alkene 23 using a phosphonate condensation, and dihydroxylation using osmium tetroxide and N-methylmorpholine W-oxide gave a mixture of the diols 24 and 25 in an 80:20, ratio. After protection of the diol 24 as its acetonide, hydrogenolysis gave the acid 27. The oxazoline 45 was deprotonated using butyllithium, and the lithiated oxazoline added to Cbz-protected leucinal 29, which had previously been deprotonated by tertbutylmagnesium chloride, to give the lactones 30 and 31, ratio 85:15, after treatment with silica in dichloromethane. Hydrogenolysis gave the aminolactone hydrochloride 52 which was condensed with the acid 27 to give the protected dipeptide 54. Deprotection under acidic conditions gave the dihydroxyazetidinone 55. Treatment with sodium hydroxide followed by acidification then gave the aminolactone hydrochloride 56 which on further treatment with sodium hydroxide followed by acid gave AI-77-B methyl ether 58. Demethylation of the phenolic methyl ether 30 followed by hydrogenolysis of the Cbz-protecting group gave the aminophenol 60 which was coupled with the acid 27 and the product taken through to AI-77-B 1 following the sequence used to prepare the methyl ether 58.

Catalytic C-H amination reactions enable direct functionalization of non-activated C(sp3)-H bonds with high levels of regio-, chemo- and stereoselectivity. As a powerful tool to unlock the potential of inert C-H bonds, C-H amination chemistry has been applied to the preparation of synthetically challenging targets since major simplification of synthetic sequences are expected from this approach. Pushing C-H amination to its limits has led to a deeper understanding of the reaction mechanism and scope. In this review, we present a description of the specific challenges facing catalytic C-H amination in the synthesis of natural products and related compounds, as well as innovative tactics created to overcome them. By identifying and discussing the major insights gained and strategies designed, we hope that this review will stimulate further progress in C-H amination chemistry and beyond.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 497-25-6. Recommanded Product: Oxazolidin-2-one

Several new sulfamidocarbonyloxyphosphonates were prepared in two steps, namely carbamoylation and sulfamoylation, by using chlorosulfonyl isocyanate (CSI), alpha-hydroxyphosphonates, and various amino derivatives and related (primary or secondary amines, beta-amino esters, and oxazolidin-2-ones). All structures were confirmed by 1H, 13C, and 31P NMR spectroscopy, IR spectroscopy, and mass spectroscopy, as well as elemental analysis. Eight compounds were evaluated for their in vitro antibacterial activity against four reference bacteria including Gram-positive Staphylococcus aureus (ATCC 25923), and Gram-negative Escherichia coli (ATCC 25922), Klebsiella pneumonia (ATCC 700603), Pseudomonas aeruginosa (ATCC 27853), in addition to three clinical strains of each studied bacterial species. Compounds 1a?7a and 1b showed significant antibacterial activity compared to sulfamethoxazole/trimethoprim, the reference drug used in this study.

An improved procedure for the three-component coupling reaction of aldehydes, amides, and dienophiles (AAD-reaction) has been developed. The use of microwave technology enables the endo-selective synthesis of N-acyl cyclohexenylamines via condensation of readily available aldehydes and amides, and subsequent Diels-Alder reaction with electron-deficient dienophiles in significantly improved yields. Advantageously, there is no need of employing additional solvents and reaction times are drastically reduced compared to similar thermal reactions.
