SmI2-Promoted novel tandem elimination and coupling reactions of aliphatic imides with carbonyl compounds: application to the synthesis of dl-isoretronecanol
Treatment of α-hetero-substituted cyclic imides with carbonylcompounds mediated by samarium(II) diiodide in the presence of HMPA was found to undergo novel tandem elimination and reductive coupling reactions to generate α-hydroxyalkylated imides in good to high yields. Stereochemistry of the coupling products was researched and the result that increasing the steric bulkiness of the N-substituents
