Variation of pH in reaction of sodium sulfide with carbonyl compounds

The results of an experimental study of how pH varies in the course of a reaction between sodium sulfite and carbonyl compounds are presented.

Method for preparing MGH by reacting sodium aldehydesulfite with MGH esterification liquid

The invention relates to a method for preparing MGH by reacting sodium aldehydesulfite with MGH esterification liquid. MGH is glyoxylic acid L-menthol ester, and the method comprises the following steps: (1) reacting an MGH esterification liquid with sodium acetaldehyde sulfite to obtain an MGH sodium salt solution; (2) reacting the MGH salt solution with acetaldehyde to obtain a mixed system containing an MGH crude product; and (3) separating and purifying the MGH crude product to obtain an MGH fine product and an acetaldehyde sodium sulfite recovery solution. The method is simple in production process, simple and convenient to operate and mild in reaction condition, obviously reduces the generation of wastewater and waste salt, and greatly reduces the investment of distillation wastewater equipment and the cost of solid waste treatment.

Direct reductive amination of aldehyde bisulfite adducts induced by 2-picoline borane: Application to the synthesis of a DPP-IV inhibitor

Aldehyde-bisulfite adducts dervied from unstable parent aldehydes were reductively alkylated in a direct fashion with a variety of amines. This approach features the use of 2-picoline borane as the reducing agent and a protic solvent for the reaction media and has been successfully applied to the synthesis of a DPP-IV inhibitor and a variety of other amines.

Synthese d'α-Hydroxysulfinates

α-hydroxysulfinates 1 (table 1) are synthesized (path b, Fig. 1), by slowly adding aldehydes 3 to the mixture sodium dithionite 4 - sodium hydroxide.Owing to their limited stability the products 1 are readily separated from sodium sulfite 5 and isolated.They are easily distinguished (table 2) from their oxydation counterparts 2.

Metabolites of the Higher Fungi. Part 19. Serpenone, 3-Methoxy-4-methyl-5-prop-1-enylfuran-2(5H)-one, a new γ-Butyrolactone from the Fungus Hypoxylon serpens (Barrons strain) (Persoon ex Fries)Kickx

Culture solutions of the fungus Hypoxylon serpens (Barrons strain) contain a new butyrolactone as the major metabolite, which has been identified as 3-methoxy-4-methyl-5-prop-1-enylfuran-2(5H)-one (2),and small quantities of the reduced analogue, 3-methoxy-4-methyl-5-propylfuran-2(5H)-one (3); the structures have been established by synthesis of compound (3).A new rapid synthesis of the isomeric 4-methoxy-3,5-disubstituted analogues is described and the two groups of compounds are compared spectroscopically.
