Abstract
The reactions of a-and gamma-substituted allylbenzotriazoles 2, 3 and 4 with an excess of lithium in THF at -78 degrees C generate various a llyllithiums, which react readily with aldehydes and ketones with high regioselectivity to give predominantly the branched products 5 in exc ellent yields.
