The electroreduction of Ar-substituted methyl cinnamates in acetonitrile gave all-trans cyclized hydrodimers stereoselectively (58-90% de). In all cases, small amounts (2-symmetric dl-3,4-diaryladipic acids and trans-3,4-diarylcyclopentanones. The chiral auxiliary [(1R)-exo]-3-exo-(diphenylmethyl)borneol, prepared from (1R)-(+)-camphor, was highly effective for the stereoselective hydrocoupling of its cinnamates by electroreduction. From the resulting hydrodimers, (3R,4R)-3,4-diaryladipic acid esters and (3R,4R)-3,4-diarylhexane-1,6-diols were synthesized in 87-95% ee.

Equation presented The chiral auxiliary [(1R)-exo]-3-exo-(diphenylmethyl)borneol, synthesized from (1R)-(+)-camphor in three steps, was highly effective for the stereoselective hydrocoupling of its cinnamates by electroreduction. From the resulting hydrod
Photoinduced Electron Transfer Reaction of Cyclopropanone Acetals with Arylmethyl Methanesulfonate: Generation of β-Keto Radical Species and Application to C-C Bond Formation

The photoinduced electron transfer reaction of the cyclopropanone acetals 1 with arylmethyl methanesulfonates 4 or 10 as electron acceptors was found to generate a transient pair of radicals, the β-keto radical 3 and the arylmethyl radical, which underwent a novel carbon-carbon formation reaction at the sterically hindered β-position of the esters.
