Addition of thionucleophiles to nitrocinnamates: approach toward synthesis of (alkyl/aryl)thio-amino acids
摘要:
The addition of alkyl or aryl thiols to alpha-nitro or beta-nitrocinnamate in the presence of base provided Michael addition products. In the case of beta-nitro compounds reaction occurred via the formation of anti-Michael adducts. Selective nitro reduction of alpha-nitroadducts gives access to beta-thio-alpha-amino acid derivatives.
