Imine allylation reactions have become a widely researched area of chemical synthesis with huge potential in fields such as natural product synthesis and the production of pharmaceutical molecules. There is a demand for effective methods of producing homoallylic amines and amides with high stereoselectivities. In this review I will discuss how through the use of catalysts, carefully selected reagents and the right conditions an imine can be allylated to afford a desired amine or amide with high yields and stereoselectivies.

I decided to rebuild my original portfolio with Next.js to fully leverage its optimisations, including Server-Side Rendering (SSR) and static rendering, both of which significantly enhance performance. To further expand its reach, I integrated next-intl to create an internationalised site that supports both English and French, ensuring a seamless experience for users in both languages.
