  Site-selective rhodium(II) acetate mediated intramolecular metal-carbene insertions into carbon-hydrogen bonds of bicyclo[2.2.1]heptanes: effcient syntheses of (+)-albene and (-)-.beta.-santalene

  摘要：

  Treatment of alpha-diazo ketones 1a-d and 2a-d with catalytic amounts of rhodium(II) acetate led to selective carbene insertions into C-H bonds resulting in cyclopentane-annulated products in high yields. The highly selective insertion realized into the exo-methyl C-H bond of 1a has been utilized in the syntheses of (+)-albene (8) and (-)-beta-santalene (11).
