Compound Q&A
How is 5,7-Dihydroxy-2-(4-hydroxyphenyl)-4-oxo-4H-chromen-3-yl 6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-galactopyranoside (CAS: 17297-56-2) typically synthesized?
Answer
This compound is typically synthesized via a multi-step process involving the coupling of a chromone derivative with a galactopyranoside through a Mitsunobu reaction, followed by an esterification step. The reaction is catalyzed by a combination of triphenylphosphine and dibutylazodicarboxylate. Yields are generally around 70%, with high selectivity towards the desired product.
