  • Esterase-catalysed regioselective 6-deacylation of hexopyranose per-acetates, acid-catalysed rearrangement to the 4-deprotected products and conversions of these into hexose 4- and 6-sulfates

    methyl α-D-mannoside 14 and methyl α-D-galactoside 16 have been selectively cleaved at the C-6 position by the esterase to give the 6-OH derivatives 5, 7, 9, 11, 13, 15 and 17. Acid-catalysed rearrangement of acetates 5, 7, 13, 15, 11, 17 and 9 with 4→6 acetyl migration gives the corresponding 4-deprotected derivatives 22–28, respectively.

    E.s.r. spectra of C-2, -3, and -4 carbohydrate free radicals, generated regiospecifically by halogen abstraction from acylated deoxyhexopyranoses are recorded in benzene solution. Analysis of the hyperfine splittings reveals the retention of 4C1 chair conformation of the parent compounds in the radicals.

    公开(公告)日:2010-01-14
    Radiolabeled tracers for sodium/glucose cotransporters (SGLTs), their synthesis, and their use are provided. The tracers are methyl or ethyl pyranosides having an equatorial hydroxyl group at carbon-2 and a C1 preferred conformation, radio-labeled with 18 F, 123 I, or 124 I, or free hexoses radiolabeled with 18 F, 123 I, or 124 I. Also provided are in vivo and in vitro techniques for using these and other tracers as analytical and diagnostic tools to study glucose transport, in health and disease, and to evaluate therapeutic interventions.

  • Regio- and Chemoselective Deprotection of Primary Acetates by Zirconium Hydrides
    作者:Marine Gavel、Thibaut Courant、Antoine Yvan Philippe Joosten、Thomas Lecourt
    DOI:10.1021/acs.orglett.8b03947
    日期:2019.4.5
    A combination of DIBAL-H and Cp2ZrCl2 is shown to promote the regioselective cleavage of primary acetates on a broad scope of substrates, ranging from carbohydrates to terpene derivatives, with a high tolerance toward protecting groups and numerous functionalities found in natural products and bioactive compounds. Apart from providing highly valuable building blocks in only two steps from biosourced raw materials, this selective de-O-acetylation should also be strongly helpful to solve selectivity issues in organic synthesis.
