title: Synthesis of N-quinonyltaurines.
abstract: Both 1,4-benzoquinones and 1,4-naphthoquinones were attached to the non-proteinogenic amino acid taurine to form N-quinonyl taurine derivatives. The products were formed via the direct Michael-like addition or by substitution of a good leaving group. An attempt to bridge the two moieties via an ureido spacer resulted in the formation of a bis-quinonylamino isocyanurate derivative. Preliminary MO calculations provided internal ground-state geometries and orbital coefficients of the HOMO levels in two representing taurine conjugates.
