The compound is a glycal derivative — a cyclic sugar bearing an enol ether double bond at the anomeric position — in which two hydroxyl groups have already been protected as acetate esters and the six position carries no hydroxyl group at all. This combination makes it a ready-to-use starting material for carbohydrate chemists who wish to construct L-configured 6-deoxy sugar units without having to carry out many separate protection and deoxygenation steps themselves.\u003c\/p\u003e\n\u003cp\u003eThe property that makes this material sought after is the characteristic reactivity of a glycal. The electron-rich double bond at the anomeric position is readily activated by Lewis acids and by electrophiles, opening the way to Ferrier rearrangement for the preparation of 2,3-unsaturated glycosides, as well as to addition reactions such as epoxidation, halogenation, and amination that allow the stereochemistry of the product to be controlled. The acetate groups act as protecting groups that remain stable during reaction yet can be removed selectively under mild basic conditions. The L configuration and the 6-deoxy pattern matter as well, because many rare sugars found in natural products and antibiotics are built on a similar framework.\u003c\/p\u003e\n\u003cp\u003eIn Indonesian laboratories, a compound of this type is typically used in university and institute research groups working on synthetic carbohydrate chemistry, natural product synthesis, and glycoscience-oriented chemical biology. It is usually purchased in small research quantities for methodology development, for the preparation of glycoside intermediates on a laboratory scale, and for postgraduate research projects where the availability of a pre-protected, pre-deoxygenated building block shortens a synthetic route considerably and improves the reproducibility of the work.\u003c\/p\u003e\n\u003ch3\u003eLaboratory Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFerrier rearrangement chemistry — the electron-rich anomeric double bond is activated by Lewis acids to give 2,3-unsaturated glycosides directly, making this a standard entry point for such routes.\u003c\/li\u003e\n\u003cli\u003eRare sugar synthesis — the L configuration together with the 6-deoxy pattern matches the framework found in many rare sugars, so the skeleton required for such targets is already in place.\u003c\/li\u003e\n\u003cli\u003eNatural product and antibiotic-related synthesis — many antibiotic sugar units are built on a comparable 6-deoxy framework, allowing this glycal to serve as an advanced intermediate rather than a raw sugar.\u003c\/li\u003e\n\u003cli\u003eStereocontrolled addition reactions — the glycal double bond undergoes epoxidation, halogenation, and amination, and these additions permit chemists to control the stereochemistry of newly formed centres.\u003c\/li\u003e\n\u003cli\u003eProtecting-group methodology studies — the two acetate esters remain stable through reaction yet can be cleaved selectively under mild basic conditions, which suits work on selective deprotection strategies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: TCI (Tokyo Chemical Industry)\u003c\/li\u003e\n\u003cli\u003eCAS number: 34819-86-8\u003c\/li\u003e\n\u003cli\u003eChemical name: 3,4-Di-O-acetyl-6-deoxy-L-glucal\u003c\/li\u003e\n\u003cli\u003eCategory: Chemistry \u0026gt; Chemical Biology \u0026gt; Glycoscience\u003c\/li\u003e\n\u003cli\u003ePack sizes: supplied in research-scale catalogue pack sizes; please refer to the current TCI listing for available options\u003c\/li\u003e\n\u003cli\u003eStorage: store as indicated on the manufacturer's label and accompanying documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHandling and Storage\u003c\/h3\u003e\n\u003cp\u003eStore the container tightly closed in a cool, dry, and well-ventilated place, away from heat, direct sunlight, moisture, and incompatible materials, and follow the storage conditions stated on the manufacturer's label and safety data sheet.
