Stereochemistry

The stereochemistry of the olefin for the allyl shift may not be correct in reference 5 and 6.

The reaction in ref. 5 is allylboration, that is, allylation of aldehyde with allylboronic acid. The explanation in "Electrophilic allyl shifts" is not correct. In this case, allylic alcohol is converted into allylboronic acid in situ by Pd catalyst and diboronic acid. Allylboronic acid reacts with benzaldehyde, which is activated by p-toluenesulfonic acid.
