2-Substituted 1,4-benzodioxanes, such as 2-cyano-, 2-methoxycarbonyl-, 2-aminocarbonyl-, and 2-formyl-1,4-benzodioxane, are key synthons that for the most part are never described as enantiomers or are inadequately characterized for enantiomeric purity. They were prepared by quantitative N,N-dichlorination of (R)- and (S)-2-aminomethyl-1,4-benzodioxane and successive functional group conversions in high yields without any racemization of the stereogenic benzodioxane C(2).

Hexokinase 2 (HK2) is over-expressed in most of human cancers and has been proved to be a promising target for cancer therapy. In this study, based on the structure of HK2, we screened over 6 millions of compounds to obtain the lead. A total of 26 (E)-N?-(2,3,4-trihydroxybenzylidene) arylhydrazide derivatives were then designed, synthesized, and evaluated for their HK2 enzyme activity and IC50 values against two cancer cell lines. Most of the 26 target compounds showed excellently in vitro activity. Among them, compound 3j showed the strongest inhibitory effects on HK2 enzyme activity with an IC50 of 0.53 ± 0.13 muM and exhibited the most potent growth inhibition against SW480 cells with an IC50 of 7.13 ± 1.12 muM, which deserves further studies.

(R)-1,4-Benzodioxane-2-carboxilic acid (R)-1 was obtained by resolution of the racemic acid 1 with stoichiometric or nonstoichiometric (+)- dehydroabietylamine (+)-2 in high chemical yield and enantiomeric excess. (S)-1 was isolated from the mother liquors of the crystallisation of (R)-1·(+)-2 and its enantiomeric excess maximised by recrystallisation procedures involving a precipitation under kinetic control or, alternatively, by conversion into the methyl ester followed by a single crystallisation. The different mechanisms of the two S enrichments is well explained by the binary phase diagrams of the acid and of the ester, which show that the former is a racemic compound, whereas the latter a conglomerate. The DSC analyses were extended to 2-hydroxymethyl- and 2-mesyloxymethyl-1,4-benzodioxane, establishing that the alcohol forms a racemic compound, while its mesyl ester a conglomerate. On the basis of these results, different resolution strategies can be designed to obtain useful homochiral 2-substituted 1,4-benzodioxanes coupling the resolution of 1 via diastereomeric salt formation with the enantiomeric enrichments by recrystallisations, preferably of its conglomerate forming derivatives.

A series of benzoxazole/benzothiazole-2,3-dihydrobenzo[b][1,4]dioxine derivatives (5a-5d and 8a-8j) was synthesized. Compounds were evaluated for binding affinities at the 5-HT1A and 5-HT2A receptors. Antidepressant activities of the compounds were screened using the forced swimming test (FST) and the tail suspension test (TST). The results indicated that the compounds exhibited high affinities for the 5-HT1A and 5-HT2A receptors and showed a marked antidepressant-like activity. Compound 8g exhibited high affinities for the 5-HT1A (Ki = 17 nM) and 5-HT2A (Ki = 0.71 nM) receptors; it also produced a decrease of the immobility time and exhibited potent antidepressant-like effects in the FST and TST in mice.

Crystallization-based resolution of 1,4-benzodioxane-2-carboxylic acid enantiomers via diastereomeric 1-phenylethylamides

Unlike the diastereomeric 1-phenylethylammonium salts, the diastereomeric N-1-phenylethylamides of (S)- and (R)-1,4-benzodioxane-2-carboxylic acid show significant differences in fusibility and solubility so as to be efficiently resolved by precipitation of the less soluble diastereomer (>98% de), while chromatographic purification of the unprecipitated fraction affords the more soluble one (>99% de). Overall, 95% of the former and 80% of the latter are recovered. The hydrolysis of the two resolved amides provides the two acid enantiomers and the resolving amine in quantitative yield and with unchanged stereoisomeric purity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Methyl 1,4-Benzodioxane-2-carboxylate, you can also check out more blogs about3663-79-4
