Reference of 21436-03-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine. In a document type is Article, introducing its new discovery.
An efficient organocatalytic methodology has been developed to perform the stereoselective addition of 2-carboxythioesters-1,3-dithiane to nitroalkenes. Under mild reaction conditions gamma-nitro-beta-aryl-alpha-keto esters with up to 92% ee were obtained, realizing a formal catalytic stereoselective conjugate addition of the glyoxylate anion synthon. The reaction products are versatile starting materials for further synthetic transformations; for example, the simultaneous reduction of the nitro group and removal of the dithiane ring was accomplished, allowing the preparation of a GABAB receptor agonist baclofen.
