- Gold(III)-Catalyzed Formal [3 + 2] Annulations of N-Acyl Sulfilimines with Ynamides for the Synthesis of 4-Aminooxazoles
-
A gold-catalyzed formal 1,3-dipolar [3 + 2] annulation using readily accessible N-acyl sulfilimines and ynamides is reported. This reaction includes the cleavage of a N-S bond and subsequent C-O bond formation. In total, 30 oxazole derivatives bearing div

- N-(4-bromobenzoyl)-S,S-dimethyliminosulfurane, a potent dermal penetration enhancer
-
N-Aroyl-, N-Arylsulfonyl-, and N-Aryl-S,S-dimethyliminosulfuranes have been synthesized and evaluated as potential dermal penetration enhancers. The title compound and Azone exhibit similar activities for permeation of hydrocortisone through hairless mouse skin.

In the reaction of N,N'-diphenylsulfonylselenium diimide (C6H5SO2N=)2Se with aldehydes, dimethyl sulfoxide, diphenyl selenone, diphenyl selenoxide, triphenylphosphine oxide, etc. the oxygen atom in the E=O group is substituted by a phenylsulfonylimino group.In the reaction of triphenylphosphine with N,N'-diphenylsulfonylselenium diimide N,N'-diphenylsulfonyl-N-triphenylphosphoniohydrazinate is formed.In the reaction of triphenylphosphine with N,N-diacylselenium or N,N'-diacylsulfur sulfimides (CH3CON=)2Se, (C6H5CON=)2Se or (C6H5CON=)2S triphenylphosphine oxide, the corresponding nitrile, and selenium or sulfur are obtained.
