Rh-catalyzed intermolecular reactions of cyclic α-diazocarbonyl compounds with selectivity over tertiary C-H bond migration

Intermolecular Rh-catalyzed reactions of cyclic α-diazocarbonyl compounds with chemoselectivity over β-hydride elimination are described. These methods represent the first general intermolecular reactions of Rh-carbenoids that are selective over tertiary

Regioselectivity control in metal hydride reductions of substituted maleic anhydrides

A systematic study of reductions of unsymmetrically substituted maleic anhydrides by a variety of metal hydride reagents indicates that the high regioselectivity observed in these reactions is controlled chiefly by electronic factors.

Reversal of Regioselectivity in the Reduction of gem-Disubstituted Cyclic Carboxylic Acid Anhydrides

The regioselective partial reduction of gem-disubstituted cyclic carboxylic acid anhydrides to the corresponding γ-lactones with LiAlH4 or NaBH4 is almost completely reversed when potassium tri-s-butylborohydride is used as the reducing agent.
