A novel and versatile access to fluorinated carbo- and heterocyclic compounds employing electron-rich fluorodienes as cycloaddition components
摘要:
The readily accessible 2-fluoro-1-trimethylsilyloxy-1,3-dienes undergo Diels-Alder type cycloaddition with a variety of dienophiles under mild conditions. In this way, fluoro-2-cyclohexenols, fluoro-2,5-dihydropyranols, fluoro-2,5-dihydro-2-pyridinols, fluoropyridines, fluoro-3,6-dihydro-1,2-oxazines and fluoropyrroles can be efficiently prepared.
The readily accessible 2-halogeno-1-trimethylsilyloxy-1,3-butadienes react smoothly with dimethyl acetylenedicarboxylate to afford 4-halophthalic esters. One of these cycloadducts was subsequently converted into heterocyclic analogues of phantolide like musk fragrances.
