The high versatility of 1-phenylsulfenyl- or 1-phenylsulfonyl-cyclopropylketones has been exploited for the regioselective synthesis of trans-2,3-disubstituted cyclobutanones, 2,4,5-trisubstituted 3,6-dihydro-2H-pyrans and cis-2-alkyl- or cis-2-aryl-cyclopropylphenylsulfones.
1-苯基硫代或1-苯基磺酰基环丙基酮的高度多功能性已被用于反式-2,3-二取代环丁酮、2,4,5-三取代3,6-二氢-2H-吡喃和顺式-2-烷基或顺式-2-芳基环丙基苯磺酰的位点选择性合成。
