Synthesis of diacetals from aldehydes and ketones with pentaerythritol catalysed by the ZrO2/S2O82- solid superacid

A manipulatively simple and rapid procedure for the synthesis of diacetals from 2,2-bis(hydroxymethyl)-1, 3-propanediol with aldehydes and ketones in refluxing benzene or toluene using the ZRO2/S2O 82- solid superacid as catalyst in 80-98% yields has been described.

Synthesis of diacetals from aldehydes and ketones with pentaerythritol catalyzed by silica sulfate under microwave irradiation

The synthesis of diacetals from pentaerythritol with aldehydes and ketones is carried out under microwave irradiation in 80-98% yields with silica sulfate as catalyst.

Synthesis of functionalised derivatives of pentaerythritol

Ring opening of the dibenzylidene derivative of pentaerythritol 12 with N-bromosuccinimide gave di-O-benzoyldibromodideoxypentaerythritol (29). Reaction of 20 and 21 with hydrogen bromide in acetic acid afforded di-O-acetyl-di-O-p-toluenesulfonyl pentaerythritol (26). Nucleophilic displacement of the tosyloxy groups in 20 by 1,2,4 triazole afforded 2-phenyl-5-(p-toluenesulfonyloxymethyl)-5-(1,2,4-triazolylmethyl)-1,3-dioxan (31) and 2-phenyl-5,5-bis(1,2,4-triazolylmethyl)-1,3-dioxan (32), and with benzotriazole gave 2-phenyl-5,5-bis(benzotriazolylmethyl)-1,3-dioxan (30). The activity of various derivatives against hepatitis B virus has been studied.

New applications of solid silica chloride (SiO2-Cl) in organic synthesis. Efficient preparation of diacetals of 2,2-bis(hydroxymethyl)-1,3-propanediol from different substrates and their transthioacetalization reactions. Efficient regeneration of carbonyl compounds from acetals and acylals

A new application of solid silica chloride, an easily available and efficient catalyst for the preparation of diacetal of 2,2-bis-(hydroxymethyl)-1,3-propanediol from aldehydes, acetals, acylals, and oximes, is described. Transthioacetalization of diacetals of 2,2-bis-(hydroxymethyl)-1,3-propanediol into their corresponding 1,3-dithianes and 1,3-dithiolanes in the presence of silica chloride is presented. Efficient regeneration of carbonyl compounds from their corresponding acetals, ketals, diacetals, and acylals in the presence of this catalyst also is described.
