Abstract
Functionalized methyl cis-4-oxoalk-2-enoates 2 are synthesized in a on e-pot procedure by singlet oxygen oxygenation of the corresponding 2-m ethoxyfurans 1 in methanol and reduction of the resulting hydroperoxid es 4 and 5 by the sulfides 6 which are selectively oxidized into the s ulfoxides 7. The synthetic method has a wide range of applicability an d affords compounds 2 stereoselectively and in good yields; concomitan tly the sulfoxides 7 are obtained in excellent yields.
