A Versatile Synthesis of Four-, Five-, and Six-membered Cyclic Ketones Using Methyl Methylthiomethyl Sulfoxide

Synthesis of Cyclopropanated Dimethyl Mercaptal Sulfoxide Pyranoses from Epoxytriflate Pyranosides and Methyl Methylthiomethyl Sulfoxide

Stereospecifically cyclopropanated sugar deriva­ tives are not only interesting from their biological point of view, but they can also serve as templates for the synthesis of natural products using the chiron approach [1]. The previous successes in the synthesis of a number of cyclopropanated sugar derivatives via diplacement of the triflyl group [2] promoted us to investigate a similar reactio...

Synthesis of five- and six-membered cyclic organic peroxides: Key transformations into peroxide ring-retaining products

The present review describes the current status of synthetic five and six-membered cyclic peroxides such as 1,2-dioxolanes, 1,2,4-trioxolanes (ozonides), 1,2-dioxanes, 1,2-dioxenes, 1,2,4-trioxanes, and 1,2,4,5-tetraoxanes. The literature from 2000 onwards is surveyed to provide an update on synthesis of cyclic peroxides. The indicated period of time is, on the whole, characterized by the devel...

Synthesis of five-membered osmacycloallenes and conversion into six-membered osmacycloallenes.

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Recent developments in the synthesis of five- and six-membered heterocycles using molecular iodine.

Heterocyclic scaffolds represent the key structural subunits of many biologically active compounds. Over the last few years iodine-mediated reactions have been extensively studied due to their low cost and eco-friendliness. This Review covers advances in the field of iodine-mediated synthesis of heterocyclic compounds since 2006, especially with an emphasis on mechanisms of ring formation. In t...
