(2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides. Formula: C16H22O11
GlucoSiFA and LactoSiFA: New Types of Carbohydrate-Tagged Silicon-Based Fluoride Acceptors for 18F-Positron Emission Tomography (PET) was written by Wiegand, Anja;Wiese, Vera;Glowacki, Britta;Iovkova, Ljuba;Schirrmacher, Ralf;Jurkschat, Klaus;Krause, Norbert. And the article was included in Synthesis in 2019.Formula: C16H22O11 The following contents are mentioned in the article:
GlucoSiFA derivatives bearing an azide or alkynyl side chain were obtained from peracetyl- D-glucose using as key step a tosylate substitution by a SiFA thiolate obtained from 4-(di-tert-butylfluorsilyl)benzenethiol. In analogy, two-fold SiFA-substituted maltose and lactose derivatives were synthesized via bistosylates. Introduction of an acetal-protecting group in β- D-azidolactose allowed the synthesis of a LactoSiFA derivative bearing only one SiFA moiety. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Formula: C16H22O11).
