Synthesis of N‐Protected Galactosamine Building Blocks from d‐Tagatose via the Heyns Rearrangement
摘要:
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.
