α-Oxoketene-S,S-, N,S- and N,N-acetals: Versatile intermediates in organic synthesis
Journal ArticleDOI
Recent developments of ketene dithioacetal chemistry.
TL;DR: This review aims to provide an intrinsic link between ketene dithioacetal groups and a variety of other functional groups, which has brought out many new facts that will assist in future designs.
Journal ArticleDOI
On the mechanism of the Skraup-Doebner-Von Miller quinoline synthesis.
TL;DR: A mechanistic pathway for the Skraup quinoline synthesis is proposed that involves a fragmentation-recombination mechanism and the aniline component condenses with the alpha,beta-unsaturated ketone initially in a conjugate fashion, followed by a fragmentation to the corresponding imine and the ketone itself.

[5 + 1] annulation : A synthetic strategy for highly substituted phenols and cyclohexenones
TL;DR: A novel [5 + 1] annulation strategy is developed for the synthesis of highly substituted phenols and cyclohexenones from alpha-alkenoyl ketenedithioacetals and nitroalkanes.
Journal ArticleDOI
Chemistry of Ketene N,S-Acetals: An Overview.
TL;DR: This review provides comprehensive knowledge on the chemistry of ketene N,S-acetals, which make them versatile and easy to use, especially in cyclization and multicomponent reactions for the synthesis of various heterocyclic systems and related natural products.
