Phthalate acid esters (PAEs), a group of xenobiotic compounds used extensively as plasticizers, have attracted increasing concern for adverse effects to human health and the
- Which anhydrosugars are used in stereocontrolled organic synthesis?
- Attention is paid mostly to anhydrosugars of great importance such as 1,6- and 1,2‑anhydrosugars, and non-anomeric sugar epoxides. Several anhydrosugars (mostly the modified ones with the nucleoside structure) show interesting biological activity, the others are used as optically pure synthons in stereocontrolled organic synthesis.
- How many chemicals can be used as plasticizers?
- There are about 30 000 chemicals can potentially be utilized as plasticizers. (1) Phthalate plasticizers are a commonly utilized compound, comprising up to 85% of the total plasticizers in the market.
- Which hydroxyl group is used in the preparation of anhydrosugars?
- The 1,4 addition of a sugar hydroxyl group to an activated electrophile is also used for the preparation of anhydrosugars. For example, treatment of 1,2- O -isopropylidene-α‑ d ‑glucofuranos-5,6‑thiocarbonate with base caused the intramolecular attack of the 3-OH anion onto the C-6 atom with formation of 3,6‑anhydro‐glucofuranose.
- What are some examples of anhydrosugars?
- The most representative are 1,6- and 1,2‑anhydro‐sugars; others are less common and have rather limited synthetic potential . The most common 1,6‑anhydrosugars are anhydro‐aldopyranoses, which are formal derivatives of 6,8‑dioxabicyclo [3.2.1]octane; less common are anhydro‐aldofuranoses.
- Are anhydrosugars biologically active products?
- Many compounds from this class are also components of biologically active products. Anhydrosugars (also called ‘intramolecular anhydrides ’) are derivatives that formally arise from elimination of the molecule of water from the parent carbohydrate.
- What are anomeric anhydrosugars?
- Anomeric anhydrosugars represent a class of molecules that can be regarded as intramolecular glycosides . The glycosydic bond may engage the terminal alcohol of a sugar molecule (1,6‑anhydropyranoses, 1,6‑anhydrofuranoses, etc.) or any other atom (1,2-, 1,3‑anhydrosugars etc.).
