  • Dibutyltin oxide mediated diastereoselective cyclodehydration/sulfonylation of 1,2,4-triols
    作者:Makhosazana P. Gamedze、Comfort M. Nkambule
    DOI:10.1016/j.tetlet.2015.02.083
    日期:2015.4
    Dibutyltin oxide (Bu2SnO) mediated cyclodehydration or sulfonylation of 1,2,4-triols is predictably diastereoselective depending on the steric bulk of the substituents at C4. A larger difference (Delta A-value >1 kcal/mol) leads to the syn-1,2,4-triols favouring cyclodehydration (78-85%) to form 3-hydroxytetrahydrofurans, with the anti-1,2,4-triols favouring monosulfonylation (66-87%). Triols from symmetrical ketones preferentially undergo cyclodehydration in high yield (>75%) due to a gem-disubstituent effect. Thus, the 1,2,4-triols derived from simple cyclic ketones also favour cyclodehydration to form spirocyclic 3-hydroxytetrahydrofurans in 72-79% yields. (C) 2015 Elsevier Ltd. All rights reserved.
  • Serendipitous synthesis of 3-hydroxy tetrahydrofurans from tin catalyzed sulfonylation of acyclic 1,2,4-triols
    作者:Makhosazana P. Gamedze、Rejoice B. Maseko、Fidelis Chigondo、Comfort M. Nkambule
    DOI:10.1016/j.tetlet.2012.08.110
    日期:2012.10
    The reaction of syn-1,2,4-triols under sulfonylation conditions catalyzed by Bu2SnO (5 mol %) results in cyclization and the formation of 3-hydroxy tetrahydrofurans (56-85%) while the anti-1,2,4-triols react to give C1-O-sulfonyl derivatives in good yields (66-83%) and the cyclization product in poor yield (5-12%). A mechanism that justifies these observations is proposed to occur via the tosylation of the primary hydroxyl followed by an intramolecular tin acetal rearrangement to a 1,3-stannylene which then undergoes a 5-exo-tet-cyclization. The difference in rates of cyclization reactivity is due to the energetically more stable tin acetals of syn-1,3-diols compared to those of anti-1,3-diols. (C) 2012 Elsevier Ltd. All rights reserved.
