Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In a patent, 70918-54-6, name is (S)-1,4-Benzodioxane-2-carboxylic acid, introducing its new discovery. Recommanded Product: 70918-54-6

We describe herein a transition-metal-free method for the decarboxylative generation of radicals from carboxylic acids and their 1,4-addition to Michael acceptors. The Fukuzumi catalyst (9-mesitylene-10-methylacridinium perchlorate, [Acr-Mes]ClO4) enabled this transformation under visible-light irradiation at room temperature with CO2 as the only byproduct. The scope and limitations of this protocol were examined by using a range of Michael acceptors (15 examples) and carboxylic acids (18 examples). The use of 3-hydroxypivalic acid in this protocol allowed the straightforward formation of a diastereomerically pure delta-lactone. Moreover, when a homoallylic acid was used, a radical cascade reaction took place with the formation of three C?C bonds.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about category: benzodioxans

Reference of 214894-89-0, Chemical Research Letters, May 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 214894-89-0, Name is 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine,introducing its new discovery.

Herein we report the iron-catalyzed beta-C(sp3)-methylation of primary alcohols using methanol as a C1 building block. This borrowing hydrogen approach employs a well-defined bench-stable (cyclopentadienone)iron(0) carbonyl complex as precatalyst (5 mol %) and enables a diverse selection of substituted 2-arylethanols to undergo beta-C(sp3)-methylation in good isolated yields (24 examples, 65% average yield).

1,4-Benzodioxane-2-carboxylic acid and isochroman-1-carboxylic acid were treated with thionyl chloride, and the resulting acid chlorides reacted with p-aminobenzoic acid in dioxane in the presence of pyridine to produce the corresponding amido acids. The latter were converted into acid chlorides which were brought into reaction with various amines to obtain a number of new diamides.

A useful and rapid access to libraries of N-arylbenzo[b]thieno[3,2-d] pyrimidin-4-amines and their pyrido and pyrazino analogues was designed and optimized for the first time via microwave-accelerated condensation and Dimroth rearrangement of the starting anilines with N?-(2-cyanoaryl)-N,N- dimethylformimidamides obtained by reaction of thiophene precursors with dimethylformamide dimethylacetal. The inhibitory potency of the final products against five protein kinases (CDK5/p25, CK1delta/epsilon, GSK3alpha/beta, DYRK1A and CLK1) was estimated. N-arylpyrido[3?,2?:4,5]thieno[3,2-d] pyrimidin-4-amine series of compounds (4a-j) turned out to be particularly promising for the development of new pharmacological inhibitors of CK1 and CLK1 kinases.
