The reaction of diaminosulfoxonium ylides with aldehydes gave the corresponding cyclopropyldiaminosulfoxonium salts in good yields when 1,8-diazabicycloundec-7-ene (DBU) was used as a base.These ylides reacted with aldehydes to give the corresponding betaines, which resulted in the formation of vinylsulfoxonium salts.The additional ylides reacted with these salts to afford cyclopropylsulfoxonium salts.The reaction of these salts with potassium hydroxide is also described.

The title compounds have been synthesized by the reaction of diaminooxosulfonium methylides with aldehydes as isomeric mixtures in good yields.These ylides reacted with aldehydes to give betaines, which formed unusual four-membered cyclic alkoxyoxosulfonium salts.Another methylide further attacked α-carbon of these salts to afford cyclopropyldiaminooxosulfonium salts.
