Abstract
N‐Acetyl‐d‐galactosamine (11), a very important naturally occurring building block of oligosaccharides, is easily accessible via the Heyns rearrangement of d‐tagatose (3) with benzylamine. The short and efficient synthesis of various differently N‐protected d‐galactosamine derivatives is reported.
