N-Methylated 5-Alkenyloxazolium Salt Transformations
摘要:
[GRAPHICS]In the course of natural product synthetic studies, 5-(4-pentenyl)oxazole and 5-(5-hexenyl)oxazole were N-methylated. The initial N-methylated 5-alkenyloxazolium salt adducts were found to be only intermediates and were ultimately transformed into hydroindole and hydroisoquinoline compounds, respectively.

Ultrasound-promoted desulfonylation of 5-substituted 4-tosyloxazoles, prepared from tosylmethyl isocyanide and carboxylic acid chlorides or by dianion chemistry, leads to 5-monosubstituted oxazoles.
