REACTIONS OF 4-METHYLENE-2-PHENYL-2-OXAZOLIN-5-ONES WITH SULFUR YLIDES
Tsuge, Otohiko,Noguchi, Michihiko,Moriyama, Hiroyuki
, p. 209 - 214 (2007/10/02)
The reaction of 2-phenyl-4-phenylmethylene-2-oxazolin-5-one with dimethyloxosulfonium methylide proceeded via a nucleophilic attack of the methylide on the carbonyl carbon in the oxazolinone with concurrent ring opening to give 1:1 adduct, dimethyloxosulf
