Aldol reactions of alpha-bromoalkyl phenyl ketones and aldehydes with Tin(IV) iodide and tetrabutylammonium iodide
Aldol reactions of alpha-bromoacetophenone and aldehydes in dichloromethane produced the corresponding E-alpha,beta-unsaturated ketones at 25 degrees C with one equimolar amount of tin(IV) iodide, one equimolar amount of tetrabutylammonium iodide and one equimolar amount of N,N-diisopropylethylamine, and produced the corresponding beta-hydroxy ketones at -80 degrees C with one equimolar amount of tin(IV) iodide and two equimolar amounts of tetrabutylammonium iodide. Using one equimolar amount of tin(IV) iodide and two equimolar amounts of tetrabutylammonium iodide at -80 degrees C in dichloromethane, alpha-bromopropiophenone reacted with aldehydes to afford the corresponding syn-alpha-methyl-beta-hydroxy ketones selectively.
