  • Zirconium-Catalyzed Hydroalumination of C═O Bonds: Site-Selective De-<i>O</i>-acetylation of Peracetylated Compounds and Mechanistic Insights
    作者:Thibaut Courant、Marine Gavel、Romain M. Q. Renard、Vincent Gandon、Antoine Y. P. Joosten、Thomas Lecourt

    日期:2021.7.16
    An unprecedented hydroalumination of C ═ O bonds catalyzed by zirconocene dichloride is reported herein and applied to the site-selective deprotection of peracetylated functional substrates. A mixed metal hydride, with 1:1 zirconium/aluminum stoichiometry, is also shown to be the reductive species. A catalytic cycle is finally proposed for this transformation with no precedent in the field of zirconium

  • 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.
  • Highly Efficient Deacetylation by Use of the Neutral Organotin Catalyst [tBu2SnOH(Cl)]2
    作者:Akihiro Orita、Yuuki Hamada、Takehiko Nakano、Shinji Toyoshima、Junzo Otera
    DOI:10.1002/1521-3765(20010803)7:15<3321::aid-chem3321>3.0.co;2-h
    日期:2001.8.3
    Deprotection of acetyl esters is effected cleanly by the neutral organotin catalyst, [tBu(2)SnOH(Cl)](2). The mildness of the reaction gives rise to great synthetic versatility and in the process a variety of functional groups are tolerated. Differentiations between primary, secondary, and tertiary alcohols and between acetyl ester and other esters are feasible. No racemization occurs with chiral acetyl esters. Exclusive deprotection of primary acetyl esters in carbohydrates and nucleosides is observed. The crude product thus obtained can be used for further reactions without purification.
