Stereochemical evidence for aryl participation in the ring opening of oxiranes. Ring-opening reactions of 1-benzyl-1,2-epoxycyclohexane under acidic conditions
SmI2-mediated reductive cleavage of α-hetero substituents of α-alkyl or α-aryl ketones and lactone gave the corresponding “thermodynamic samarium enolates”. Enantioselective protonation of the samarium enolates with C2-symmetric chiral diols afforded the corresponding ketones and lactone in moderate to high enantioselectivities.
