摘要

Aldehydes and ketones are converted into the corresponding alkenes via hydroboration of their enamines. Hydroboration of aldehyde enamines by 9-borabicyclo [3.3. llnonane (g- BBN), followed by methanolysis, affords the corresponding terminal alkenes in 7590% yields. Unsaturated aldehyde enamines produce the corresponding dienes under these conditions. Enamines derived. from substituted cyclic ketones and heterocyclic ketones ...
