Abstract

1-Aryl-2-benzoylethylenes react with dimethyloxosulfonium methylide in dimethylformamide and form trans 1-aryl-2-benzoylcyclopropanes, the configuration of which was confirmed by double 13C NMR spectroscopy. The reaction proceeds exclusively at the double bond adjacent to carbonyl group with 1-aryl-4-benzoylbuta-1, 3-dienes and 1-aryl-6-benzoylhexa- 1, 3, 5-trienes and leads to trans 1-(2′-(aryl) vinyl)-2-benzoylcyclopropanes and trans 1-( ...
