Unlabeled 1,3–Dithiane is a versatile reagent able to act as an acyl anion equivalent when submitted to Corey-Seebach reaction conditions.1 This well known chemistry can also be carried out when 1,3–Dithiane is labeled at the 2 position providing labeled and protected aldehydes, ketones, α-hydroxyketones, 1,2–diketones and α-keto acid derivatives. Deprotection can be facilitated using standard methods to give the appropriately labeled substrates (Scheme 1).2

Scheme 1: 1,3–Dithiane for the introduction of D and/or 13C.
