Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (S)-(2,2-dimethyl-[1,3]-dioxolan-4-yl)-methylamine, is researched, Molecular C6H13NO2, CAS is 82954-65-2, about Direct conversion of (R)-epichlorohydrin to (S)-3-aminopropane-1,2-diol: an important chiral C-3 building block.Safety of (S)-(2,2-dimethyl-[1,3]-dioxolan-4-yl)-methylamine.

A new and effective method for the preparation of (S)-3-amino-1,2-propanediol was established starting from (R)-epichlorohydrin. The synthetic approach involves the reaction of (R)-epichlorohydrin with acetone catalyzed by BF3·OEt2 to give (R)-4-(chloromethyl)-2,2-dimethyl-1,3-dioxolane. Subsequent replacement of the Cl with NH2 group by azidation followed by reduction gave ((S)-2,2-dimethyl-1,3-dioxolan-4-yl)methanamine, which was converted into (S)-3-aminopropane-1,2-diol·HCl by acetal deprotection with MeOH·HCl.

Let’s learn more about this compound (cas:27469-61-0).

A new series of 3-(3-pyridyl)acrylamides, e.g., I (R = H, R1 = 4-F, 4-Cl, 4-OMe, 3-Me, 4-Me, R2 = H, 4-Cl, 4-Me; R = 2-Cl, 2-NHMe, 2-Me, 5-F, 5-Cl, 5-Br, 5-OMe, 5-OH, 6-Cl, 6-OMe, 6-Me, 6-Bu, R1 = R2 = H), and 5-(3-pyridyl)-2,4-pentadienamides, e.g., II (R = H, Me, n = 3,4) were prepared and evaluated for antiallergic activity. Several of these compounds exhibited more potent inhibitory activities than the parent compound I (R = R1 = R2 = H) against the rat passive cutaneous anaphylaxis (PCA) reaction and the enzyme 5-lipoxygenase. Particularly, I (R = 6-Me, R1 = R2 = H) (III) showed an ED50 value of 3.3 mg/kg po in the rat PCA test, which was one-fifth of ketotifen and oxatomide. As compared with ketotifen and oxatomide, III showed a better balance of antiallergic properties due to inhibition of chem. mediator release, inhibition of 5-lipoxygenase, and antagonism of histamine.

Designer Receptors Exclusively Activated by Designer Drugs (DREADD) are a preclin. chemogenetic approach with clin. potential for various disorders. In vivo visualization of DREADDs has been achieved with positron emission tomog. (PET) using 11C radiotracers. The objective of this study was to develop DREADD radiotracers labeled with 18F for a longer isotope half-life. A series of non-radioactive fluorinated analogs of clozapine with a wide range of in vitro binding affinities for the hM3Dq and hM4Di DREADD receptors has been synthesized for PET. Compound [18F]7b was radiolabeled via a modified 18F-deoxyfluorination protocol with a com. ruthenium reagent. [18F]7b demonstrated encouraging PET imaging properties in a DREADD hM3Dq transgenic mouse model, whereas the radiotracer uptake in the wild type mouse brain was low. [18F]7b is a promising long-lived alternative to the DREADD radiotracers [11C]clozapine ([11C]CLZ) and [11C]deschloroclozapine ([11C]DCZ).
