Title compound I, labeled with ¹⁴C in the 2-position, was prepared in 30.7% yield by cyclocondensation of NH₂CH₂CH₂SH with ¹⁴C-labeled CH₂O in H₂O at pH = 8, followed by nitrosylation of the thiazolidine with NaNO₂ at pH = 4.5 adjusted with H₂SO₄. Adjustment of the pH in the latter step with HCl forms many disulfide byproducts.

Ge, Dandan published the artcilePreparation of new hydrophobic deep eutectic solvents and their application in dispersive liquid-liquid microextraction of Sudan dyes from food samples, Category: chlorides-buliding-blocks, the publication is Analytical and Bioanalytical Chemistry (2021), 413(15), 3873-3880, database is CAplus and MEDLINE.

In this work, a new generation of hydrophobic deep eutectic solvents (DESs) was prepared using eugenol (as hydrogen bond donor) and benzyltriethylammonium bromide, benzyltributylammonium bromide, benzyltriethylammonium chloride and benzyltributylammonium chloride (as hydrogen bond acceptor) in different molar ratios. These DESs were applied to vortex-assisted dispersive liquid-liquid microextraction of Sudan dyes from food samples, followed by high-performance liquid chromatog. determination The influencing parameters, including the type of DES, amount of DES, extraction time, solution pH and salt addition, were investigated and optimized. Under the optimized conditions, a linear range of 2-1000 ng mL-1 with determination coefficients of <0.999 was obtained. Limits of detection and limits of quantification were in the range of 0.5 to 1 ng mL-1 and 2 to 3 ng mL-1, resp. The proposed method was successfully used in the determination of Sudan dyes in chili sauce, chili powder and ketchup, and satisfactory recoveries of between 89.9 and 119.3% were obtained, with relative standard deviations in the range of 0.1-6.8%. The proposed method is simple, green and efficient, and can be applied to determine Sudan dyes in complex matrixes.

A highly enantioselective, organocatalytic intramol. cyclization by a Friedel-Crafts-type 1,4-addition using a Joergensen-Hayashi-like organocatalyst with a large silyl protecting group and showed that heat improved the reaction yield with virtually no detriment to enantioselectivity. A variety of bicyclic resorcinols were obtained with excellent enantioselectivities (up to 94%). To show the utility of these constructs, and as part of a wider project involved the synthesis of cannabinoid-like compounds, the resorcinol formed was used to generate both ‘normal’ and ‘abnormal’ cannabidiol which had anticonvulsant activity.
