Hypervalent iodine (III)-intermediated direct oxidative rearrangement of 3-hydroxybut-2-enimidates affording oxazoles under mild conditions has been developed. This protocol provides a new methodology to the synthesis of compounds containing oxazole structure.

Seven new substituted 5-phenoxy-1,2,4-dithiazole-3-ones were prepared in modest yield (53-76%) from corresponding O-phenyl thiocarbamates and chlorocarbonylsulfenyl chloride in dry ether at-10 °C. All of the compounds were characterized by NMR and elemental analysis and some of them by X-ray diffraction. Preliminary kinetic measurements showed that the parent 5-phenoxy-1,2,4-dithiazole-3-one is a very efficient sulfurizing agent toward triphenyl phosphite. Copyright
Interaction of aryloxychlorocarbenes with acetylenedicarboxylate: Novel formation of polyfunctional butadienes and 8-oxatricyclo[3.2.1.0 2.4]oct-6-enes

The interaction of aryloxychlorocarbenes with dialkyl acetylenedicarboxylates has been examined. Thermolyses of 3-aryloxy-3- chlorodiazirines in the presence of acetylenedicarboxylate resulted in the formation of unexpected polyfunctional 1,3-butadienes and 8-oxatricyclo[3.2.1. 02.4]oct-6-enes or of 2-aryoxycarbonylmaleates dependent upon reaction conditions. This work confirmed the nucleophilicity of aryloxychlorocarbenes and underlined their synthetic potential.
