  Electron-Transfer-Induced Reductive Cleavage of Phthalans:  Reactivity and Synthetic Applications

  摘要：

  The behavior of phthalan (1a) was investigated under conditions of electron transfer from alkali metals in aprotic solvents. Reaction with lithium in the presence of a catalytic amount of naphthalene in THF led to the reductive cleavage of an arylmethyl carbon-oxygen bond, with formation of a stable dilithium compound. Trapping of this intermediate with several electrophiles (alkyl halides, carbonyl derivatives, CO2) was successful. The extension of this procedure to several substituted phthalans (1b-i) was investigated, and the regiochemistry as well as the synthetic usefulness of these reactions are discussed.

  DOI：10.1071/ch9802699

  日期：——

  Several 3-aminobenzylphthalides have been prepared by reactions of 3- (2-oxo-1-phenylpropyl)-phthalides with hydrazoic acid or by the Beckmann rearrangement. The corresponding reactions with 3-(2- oxoindanyl)phthalides showed limited success but led to a new synthesis of phthalide-isoquinoline alkaloids. Preliminary biological testing of some of these derivatives indicates that they only have weak central nervous system activity.

  of a stable aromatic dilithium compound. The adducts of the latter with CO2, aldehydes or ketones undergo ring closure to isochroman derivatives, leading to ring expansion of the original heterocycle. The reductive electrophilic substitution procedure was successfully extended to the substituted phthalans 1b and 1c, to afford the corresponding isochroman-3ones in satisfactory yields.

• Lithiation Reactions Catalyzed by Linear and Cross-Linked Arene-Based Polymers. Generation of Functionalized Organolithium Compounds
  作者：P. Candela、C. Gómez、M. Yus

  DOI：10.1023/b:rujo.0000044541.84132.e5

  日期：2004.6

  Lithiation of various substrates, such as chlorinated acetals, alpha-chloro ether, dichloro derivatives, benzo-fused heterocycles, and allyl and benzyl derivatives, with excess lithium powder in the presence of a catalytic amount of soluble linear or insoluble cross-linked arene (naphthalene or biphenyl)-based polymers yields the expected organolithium intermediates. The latter react with electrophiles either in two steps or under Barbier-type reaction conditions to afford the corresponding adducts. The catalyst is easily recuperated by filtration at the end of the process, and the procedure can be regarded as a reasonable alternative to the use of free arenes as electron carrier in lithiation reactions.
