Treatment of 4-amino-4-phenyl-butan-2-ol with mesyl chloride, followed by displacement with amine nucleophiles resulted in a 1,3 rearrangementvia an azetidinium cation intermediate. This rearrangement has been proven to proceed via a double inversion of stereocentres at positions 1 and 3.

chemokine receptor 5 (CCR5) near an allosteric binding site for the drug maraviroc. We then used molecular dynamics simulations to design heterobifunctional maraviroc analogues consisting of a drug fragment connected by a flexible linker to a reactive moiety capable of undergoing a bioorthogonal coupling reaction. We synthesized a library of these analogues and employed the bioorthogonal inverse electron
