Abstract

This paper describes the synthesis and structural studies of N‐(p‐toluenesulfonyl)‐amino acid 3,5‐di‐tert‐butyl‐2‐phenolamides by ^1^H, ^13^C, and ^15^N. The presence of intra‐ and __inter__molecular hydrogen bonds were studied by variable temperature NMR spectroscopy. The molecular structure of two amides in the solid state was determined by X‐ray diffraction experiments. The results show that tert‐butyl substituents in the phenolic ring have important effects in the nature of hydrogen bonds and conformation of these amides. © 2004 Wiley Periodicals, Inc.
