To showcase the versatile utility of these homoallylic amines as synthetic precursors for bioactive molecules, various cyclizations were carried out using compounds 3ab and 3bb (Scheme 2). In a procedure by Jin et al., the allyl group can undergo iodination followed by 4-exo-tet ring closure to generate azetidine 4aa. In the presence of heat, pyrrolidines can be selectively synthesized, or isomerized from the azetidines. In our experience, the para-position on the aniline ring must be occupied otherwise iodination can occur (4ab, see supporting information). In some cases, this can be favorable for further modifications via cross coupling. Isolating the pyrrolidine after isomerization proved difficult, hence a hydroboration/oxidation/cyclization approach was preferable. Reacted for 20 min at 70 °C 83 NMR yields using toluene as the internal standard. a Ratio consists of 0.5 mL total solvent.
