Preparation of 1,4-Dienes from 2-(2-Hydroxyalkylseleno)benzothiazoles by the Reaction Involving Se -> O Azaaromatic Ring Rearrangement

The reactions of 2-(2-oxoalkylseleno)benzothiazoles with allylic Grignard reagents in the presence of BF3*OEt2 gave the corresponding 2-benzothiazoles which, on treatment with Ph3P and NaH, afforded 1,4-dienes in good to excellent yields.

Preparation of 1,4-Dienes from 2-(2-Hydroxyalkylseleno)benzothiazoles by the Reaction involving Se->O Aza-aromatic Ring Rearragement

The reaction of 2-(acylmethylseleno)benzothiazoles with allylic Grignard reagents in the presence of BF3*OEt2 gave the corresponding 2-(2-hydroxyalkylseleno)benzothiazoles which, on treatment with NaH and Ph3P, afforded 1,4-dienes in good to excellent yields.
