Unusual, strained heterocycles: 3-Alkylidene-2-methyleneoxetanes from Morita-Baylis-Hillman-type adducts

10.1021/ol020202v

The researchers successfully synthesized 3-alkylidene-2-methyleneoxetanes and explored their reactivity, demonstrating their potential as synthetic scaffolds. They also unexpectedly found that electron-rich 3-aryl-2-methylene-3-hydroxy acids could be converted into electron-rich aryl allenes at room temperature. Key chemicals used in the process include dimethyltitanocene, various Morita?Baylis?Hillman-type adducts, and reagents like o-nitrobenzenesulfonyl chloride for lactonization, as well as DMDO for the chemoselective oxidation of enol ethers and MgBr2 in the exploration of Diels-Alder reactivity.
