N-[Bis(methylthio)methylene]-p-toluenesulfonamide

Short Synthesis of (+)‐Cylindricine C by Using a Catalytic Asymmetric Michael Reaction with a Two‐Center Organocatalyst

“…These structurally related compounds exhibit bioactivity against a DNA‐repair‐deficient yeast strain4 and also inhibit the growth of murine leukemia and human solid‐tumor cell lines 5. Their tricyclic ring system (see Scheme ) is comprised of a spirocyclic amine that makes them an attractive target for total synthesis 6…”
