Favorskii rearrangement of α-chloro β-keto sulfones with amines: A new synthesis of amides and α,β-unsaturated amides from aldehydes and ketons

The Favorskii rearrangement of α-chloro β-keto sulfones, which are easily synthesized from aldehydes and ketones, with amines gives β-sulfonyl amides in good yield. These β-sulfonyl amides are converted to amides and α,β-unsaturated amides by reduction or elimination of the sulfonyl group.

A new synthesis of 2-sulfanyl allylic alcohols and α-sulfanyl ketones from carbonyl compounds and 1-chloroalkyl p-tolyl sulfoxides with carbon-carbon bond-formation

Reaction of lithium α-sulfinyl carbanions of 1-chloroalkyl p-tolyl sulfoxides with ketones or aldehydes at low temperature gave adducts in almost quantitative yields. Treatment of the adducts derived from ketones with trifluoroacetic anhydride (TFAA) in t

Favorskii Rearrangement and Carbon-Carbon Bond-Cleavage of α-Chloro-α-sulfonyl Ketones: A Synthesis of Carboxylic Acids and Their Derivatives from Aldehydes and Ketones

A method for synthesizing carboxylic acids and their derivatives from aldehydes and ketones via α-chloro-α-sulfonyl ketones is described.Acyclic α-chloro-α-sulfonyl ketones were synthesized from aldehydes and 1-chloroalkyl p-tolyl sulfoxides with carbon-carbon coupling in good overall yields.Cyclic α-chloro-α-sulfonyl ketones were synthesized from cyclic ketones in three steps in high overall yields.The Favorskii rearrangement of both acyclic and cyclic α-chloro-α-sulfonyl ketones with sodium hydride in the presence of amine gave β-sulfonyl amides with skeletal rearrangement in good to excellent yield.Amides and α,β-unsaturated amides were synthesized from the β-sulfonyl amides.Treatment of the cyclic α-chloro-α-sulfonyl ketones with alkoxides and hydroxide gave carboxylic esters and acids with cleavage of the ring in good to excellent yields.

Lithium-Chlorine Exchange Reaction of α-Chloro α-Sulfonyl Ketones

Lithium-chlorine exchange of α-chloro α-sulfonyl ketones, easily prepared from 1-chloroalkyl aryl sulfoxides and aldehydes in good yields, with n-butyllithium gave α-sulfonyl ketones in high yields.Some trials to trap the enolate intermediate were carried

A NOVEL SYNTHESIS OF HALOALKENES FROM ALDEHYDES WITH CARBON-CARBON COUPLING

Treatment of α-halo β-mesyloxy sulfoxides, easily synthesized from aldehydes and 1-haloalkyl aryl sulfoxides in two steps, with n-BuLi at -78 deg C gives haloalkenes in good yields. Key words: Sulfoxide; 1-haloalkyl aryl sulfoxide; fluoroalkene; chloroalk

1-Chloroalkyl p-Tolyl Sulfoxides as Useful Agents for Homologation of Carbonyl Compounds: Conversion of Carbonyl Compounds to α-Hydroxy Acids, Esters, and Amides and α,α'-Dihydroxy Ketones

One-carbon homologation of carbonyl compounds to α-hydroxy acids, esters, and amides by the use of 1-chloroalkyl p-tolyl sulfoxide as a hydroxycarbonyl anion equivalent is reported.Oxidation of the vinyl chlorides, the intermediates of the above-mentioned
