Triacetonide of Glucoheptonic Acid in the Scalable Syntheses of d‑Gulose, 6‑Deoxy‑d‑gulose, l‑Glucose, 6‑Deoxy‑l‑glucose, and Related Sugars

Ease of separation of petrol-soluble acetonides derived from the triacetonide of methyl glucoheptonate allows scalable syntheses of rare sugars containing the l-gluco or d-gulo structural motif with any oxidation level at the C6 or C1 position of the hexose, usually without chromatography: <i>meso</i>-d-glycero-d-guloheptitol available in two steps is an ideal entry point for the study of the biotechnological production of heptoses
