Description
Rachael Hamilton led a team reporting a new asymmetric reaction in a 2024 paper. Their method rearranges a class of starting materials called allenoates into useful building blocks. A cheap, easy-to-handle acid on silica served as the catalyst, in a small amount. An attached helper group steered which face of the molecule gets attacked, favoring one mirror form strongly.
The helper could be washed off afterward and recovered in high yield for reuse. Products came out in near-perfect yield and purity of the favored mirror form. A two-center example gave a strong preference for one arrangement of the two new centers. The work offers a practical route to chiral building blocks.
