Evaluation of Oxidative Stress in Biological Samples Using the Thiobarbituric Acid Reactive Substances Assay.
Aguilar Diaz De Leon J, Borges CR. Aguilar Diaz De Leon J, et al. J Vis Exp. 2020 May 12;(159):10.3791/61122. doi: 10.3791/61122. J Vis Exp. 2020. PMID: 32478759 Free PMC article.
Pure MDA is unstable, but these conditions allow the release of MDA from MDA bis(dimethyl acetal), which is used as the analytical standard in this method. The TBARS assay is a straightforward method that can be completed in about 2 h. ...

An improved synthesis of azedarachol.
Ran G, Weisheng T. Ran G, et al. Steroids. 2022 Oct;186:109072. doi: 10.1016/j.steroids.2022.109072. Epub 2022 Jun 20. Steroids. 2022. PMID: 35738310
An improved synthesis of azedarachol is reported in 10 steps with an overall yield of 12% from pregnanetriol. A proper use of p-anisaldehyde dimethyl acetal provided a chance of regioselective reduction of 2-enepregnane-16R,20R-p-anisaldehyde acetal(6) and in turn a …

Acetaldehyde in the Enders triple cascade reaction via acetaldehyde dimethyl acetal.
Brusa A, Iapadre D, Casacchia ME, Carioscia A, Giorgianni G, Magagnano G, Pesciaioli F, Carlone A. Brusa A, et al. Beilstein J Org Chem. 2023 Aug 24;19:1243-1250. doi: 10.3762/bjoc.19.92. eCollection 2023. Beilstein J Org Chem. 2023. PMID: 37674523 Free PMC article.
Herein, we report the Enders-type cascade reaction using acetaldehyde dimethyl acetal, as a masked form of acetaldehyde. This strategy directly converts acetaldehyde, nitroalkenes and enals into stereochemically dense cyclohexenals in good yield and excellent …

Synthesis of Tunable Fluorescent Imidazole-Fused Heterocycle Dimers.
Zheng Q, Li X, Kurpiewska K, Dömling A. Zheng Q, et al. Org Lett. 2022 Jul 22;24(28):5014-5017. doi: 10.1021/acs.orglett.2c01642. Epub 2022 Jul 13. Org Lett. 2022. PMID: 35830622 Free PMC article.
A short, concise, and one-pot synthesis of imidazo-fused heterocycle dimers with tunable fluorescent properties has been developed. By the first time use of glyoxal dimethyl acetal in the Groebke-Blackburn-Bienayme (GBB) three-component reaction (3CR), the innovatio …
