an efficient method for the synthesis of 1-substituted homotaurines. Homotaurine and a series of 1-substituted homotaurines were readily synthesized in satisfactory to good yields via the Michael addition of thioacetic acid to aliphatic and aromatic α,β-unsaturatednitriles followed by lithium aluminum hydride mediated reduction and performic acid oxidation. The synthesis of 1,1-disubstituted homotaurines

The present application relates to a conjugate comprising an amatoxin, a target-binding moiety wherein the target is CD20, i.e., a CD20-binding moiety, and optionally a linker linking said amatoxin and said CD20-binding moiety. The invention further relates to the synthesis of said conjugate. In addition, the invention relates to a pharmaceutical composition comprising such conjugate, particularly for use in the treatment of B-cell and/or lymphoma associated diseases and/or malignancies.

Various substituted homotaurines (=3‐aminopropane‐1‐sulfonic acids) 6 were readily synthesized in satisfactory to good yields via the Michael addition of thioacetic acid to alk‐2‐enamides 3 (→4), followed by LiAlH4 reduction (→5) and performic acid oxidation (Scheme 1). The configuration of ‘anti’‐disubstituted homotaurine ‘anti’‐6h was deduced from the 3‐(acetylthio)alkanamide (=S‐(3‐amino‐1,2‐dimethyl‐3‐oxopropyl)
