Abstract A synthetic pathway to functionalized six-membered dilactones structurally analogous to lactide is described. Through the use of orthogonal protecting groups, the synthesis of functionalized dilactones was performed in a straightforward way by cyanuric chloride-mediated cyclization of the corresponding linear α-hydroxy acid dimers. The synthesis of three different dilactones− methylglycolide, benzyloxymethylglycolide, and 2- ...
