• A Method for the Net Contra-thermodynamic Isomerization of Cyclic Trisubstituted Alkenes
  作者：Raphaël F. Guignard、Laurent Petit、Samir Z. Zard

  DOI：10.1021/ol4018744

  日期：2013.8.16

  A simple sequence for the net contra-thermodynamic isomerization of cyclic trisubstituted alkenes is reported consisting of a radical addition of p-chlorothiophenol, followed by oxidation to the sulfoxide and thermal syn-elimination to give the least substituted isomeric cycloalkene.

  has been prepared, containing a chiral oxazoline ring and as a second chiral unit a bis(N-sulfonylamino)phosphine group embedded in a diazaphospholidine ring or a cyclic phosphite group derived from TADDOL. These modular ligands are readily synthesized from chiral amino alcohols and chiral 1,2-diamines or TADDOLs. Palladium and iridium complexes derived from these ligands were found to be efficient catalysts

  An operationally simple and broadly applicable novel cyclopropanation of styrenes using gem-diiodomethyl carbonyl reagents has been developed. Visible-light triggered the photoinduced generation of iodomethyl carbonyl radicals, able to cyclopropanate a wide array of styrenes with excellent chemoselectivity and functional group tolerance. To highlight the utility of our photocyclopropanation, we demonstrated

  transformed into 8-methoxytetralins through the action of zirconium tetrachloride. Yields are generally good though turnover is slow. Ultrasonic irradiation, phase transfer catalysts, crown ethers and lithium chloride all accelerate the reaction which proceeds via scission of the C-1 to C-8a bond and cyclisation by intramolecular Friedel-Crafts alkylation.

  可以通过四氯化锆的作用将6-甲氧基四氢化萘转化为8-甲氧基四氢化萘。尽管周转缓慢，但产量总体上还是不错的。超声辐射，相转移催化剂，冠醚和氯化锂都可加速反应，该反应通过C-1至C-8a键的断裂和分子内Friedel-Crafts烷基化环化而进行。
