As two potential routes from 3 to 7 may be envisioned (Scheme 1) we sought to clarify the mechanism of reaction. The potential intermediate N-allyl-5-hydroxypentan-1-amine (4v) was synthesised and subjected alongside 4 to an oxidase activity screen as outlined previously. As 4 was shown to be a substrate for AcCO6 whilst 4v was not, we concluded that "Route A" was the mechanism by which the heterocycle was formed. Following this, we sought to establish a product scope for this cascade reaction.
