Abstract A convenient procedure for the synthesis of homoallylic alcohols from carbonyl compounds and allylboranes is described. Allyl-, 2-methylallyl-, crotyl-and 3, 3-dimethylallyl (dialkyl) boranes, as well as diallyl (alkyl) boranes and derivatives of 3-allyl-and 3-metallyl-3- borabicyclo [3.3. 1] non-6-ene are effective reagents for allylation of carbonyl compounds (aldehydes, ketones, esters, carboxylic acids and others) offering, in a number of cases, ...
