1,25-Dihydroxyvitamin D3 [1,25(OH)2D3] has potent antiproliferative actions but calcemic effects obstruct its application in the treatment of hyperproliferative disorders. Therefore, analogs of 1,25-(OH)2D3 are designed with a clear dissociation between both effects. Here the biological activity of the trans-decalin CD-ring

An unprecedented and highly diastereoselective 6-endo-trig cyclization of 2-alkenyl-1,3-dithiolanes has been developed yielding trans-decalins, an important scaffold present in numerous di- and triterpenes. The novelty of this 6-endo-trig cyclization stands in the stepwise mechanism involving 2-alkenyl-1,3-dithiolane, acting as a novel

The hydrophobicity of surfactants has been described through different concepts used to guide the formulation of surfactant-water (SW) and surfactant-oil-water (SOW) systems. An integrated framework of hydrophobicity indicators could provide a complete tool for surfactant characterization, and insights on how
