Treatment of α-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 (-)-β-santalene (11).
