Ethyl lactate mediated thioacetalization of aldehydes at ambient temperature

Dithioacetalization reactions of aldehydes with thiols/thiophenols have been successfully achieved at room temperature by employing the green, bio-based ethyl lactate as the reaction medium. By means of this sustainable approach, a class of dithioacetals has been acquired with high diversity and efficiency.

Highly efficient and chemoselective method for the thioacetalization of aldehydes and transthioacetalization of acetals and acylals catalyzed by H 2SO4-silica under solvent-free conditions

Chemoselective and efficient thioacetalization of a variety of aldehydes was achieved in excellent yields at room temperature using 1,2-ethanedithiol in the presence of catalytic amounts of H2SO4-silica. Thioacetals were also prepare

Oxidative cross-esterification of dithiolanes with alcohols through a cross-dehydrogenative coupling (CDC)/deprotection sequence

An unprecedented oxidative cross-esterification in an equimolar mixture of dithiolanes, alcohols and water through a CDC/deprotection sequence has been developed. The reaction itself features simple experimental procedures under very mild conditions and offers a new strategic protocol for the direct and efficient synthesis of structurally diverse esters.

An efficient method for the transthioacetalization of acylals and acetals under mild conditions

A rapid and efficient method for the transthioacetalization of acylals (1,1-diacetates) and acyclic and cyclic acetals is described. The reaction was carried out using 1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane tribromide (1 mol%). The yield of the transthioacetalization was high and reaction conditions involve the use of acetonitrile as the solvent at room temperature; isolation is simple and the products are nearly pure.

Silica-supported phosphorus pentoxide: A reusable catalyst for S,S-acetalization of carbonyl groups under ambient conditions

Phosphorus pentoxide supported on silica gel (P2O 5/SiO2) efficiently acts as a highly active and reusable catalyst for cyclic and non-cyclic S,S-acetalization of a variety of carbonyl compounds under mild, solvent-free an

An efficient method for chemoselective thioacetalization of aldehydes in the presence of a catalytic amount of acidic ionic liquid under solvent-free conditions

A water-stable Br?nsted acidic ionic liquid with an alkane sulfonic acid group was synthesized. This ionic liquid catalyzed the thioacetalization reaction smoothly to afford 1,3-dithianes in excellent yield and less time. In this article we describe a mil

Chemoselective and solvent-free thioacetalization of aldehydes by a catalytic amount of NBS

A chemoselective, straightforward, and rapid method for thioacetalization of aldehydes by use of 1,2-ethandithiol and a catalytic amount of N-bromosuccinimide under solvent-free conditions is reported. The reaction takes place in excellent yields and shor

A mild and chemoselective dithioacetalization of aldehydes in the presence of anhydrous copper (II) sulfate

Various aldehydes have been protected with different thiols as dithioacetals with excellent yields using anhydrous copper sulfate as a mild and chemoselective catalyst. The reaction is carried out in a solvent and/or under solvent-free conditions. The transthioacetalization of oxyacetals into dithioacetals was also achieved in an excellent yield.

A mild and chemoselective catalyst for thioacetalization under solvent free conditions

Protection of a variety of carbonyl compounds as dithioacetals using P 2O5/SiO2 (75%), as a mild and chemoselective catalyst, was achieved under solvent free conditions in very good yields. Copyright Taylor & Francis Group

Ruthenium(III) chloride-catalyzed thioacetalization of carbonyl compounds: Scope, selectivity, and limitations

A variety of carbonyl compounds can be easily and rapidly converted to the corresponding cyclic and acylic dithioacetals in the presence of a catalytic amount of ruthenium chloride in acetonitrile at room temperature. Some of the major advantages of this
