Erythrina alkaloids represent a rich source of complex polycyclic, bioactive natural products. In addition to their sedative and hypotensive effect, their curare-like activity and structural framework have made them attractive targets for synthetic and medicinal chemists. (+)-Dihydro-beta-erythroidine (DH beta E), the most potent nicotine acetylcholine receptor antagonist (nAChR) of the Erythrina family, is synthesized for the first time in 13 steps from commercially available material.

A new and efficient class of double-allylation reagents, α-trimethylsilylmethyl allylboronate 1 and the crotylboronates 12, is reported. These stable bimetallic reagents are prepared easily in enantiomericallypure form and add under BF3 catalysis onto a wide range of aldehydes to afford a direct access to hydroxyl-functionalized allylic silanes in very high E/Z selectivity and excellent enantioselectivity
