Syntheses, electrochemistry and molecular modeling of N,N′-dicyanoquinonediimine (DCNQI) derivatives of substituted 1,4-anthracenediones: Precursors for organic metals

The title compounds (10) have been obtained from the corresponding 1,4-anthracenedione derivatives (3), prepared by different synthetic routes, by reaction with bis(trimethylsilyl) carbodiimide (BTC). The cyclic voltammetry of these compounds (3 and 10) reveals the presence of two reduction waves to the corresponding anion-radical and dianion. The acceptor ability of compounds 10 can be modulated by the presence of substituents on the DCNQI ring. The syn/anti isomers have been studied by molecular mechanics and the results are in good agreement with the 1H-NMR high resolution spectral data.

Unusual, chemoselective etherification of 2-hydroxy-1,4-naphthoquinone derivatives utilizing alkoxymethyl chlorides: Scope, mechanism and application to the synthesis of biologically active natural product (±)-lantalucratin C

A novel etherification of 2-hydroxy-1,4-naphthoquinone derivatives with alkoxyalkyl chlorides and hydride bases is described. Precise study of the conditions and substrate scope suggested that the reaction occurs specifically in the molecule having a 2-hydroxy-1,4-benzoquinone skeleton. A chemoselective O-methylation reaction was achieved to afford a synthetically important intermediate, which offered easy access to a natural product possessing anti-tumor activity.

Chemoselectivity in the Reaction of Metal Phenolates with Aromatic Dialdehydes

Oxophilic metal phenolates undergo highly selective condensations with aromatic dialdehydes to produce compounds 6,7,11 and 12 resulting from di- or tetra-attack, depending upon the phenol-aldehyde molar ratio. 1,4-Anthraquinones 17 were synthesized by allowing 1,4-hydroquinones to react with phthalaldehyde (OPA).

Obtention of anthraquinones by selective oxidation of the corresponding anthracenes and 9,10-dimethoxyanthracenes with copper or zinc nitrate supported on silica gel

Anthracene, 9,10-dimethoxyanthracene and substituted analogues are selectively oxidized to the corresponding anthraquinones in good yields by copper(II) or zinc(II) nitrate supported on silica gel; the ether groups at different position from 9 and 10 are unaffected.

Synthesis method for reductant precursor

A synthesis method is provided for the synthesis of quinone compounds of the formula STR1 where n is 0-3, Y1 is alkoxy, Y2 is alkoxy, chloro, bromo or hydrogen and R' and R" each and independently are hydrogen, alkyl or phenyl. These compounds are useful as reductant precursors in tellurium imaging compositions.
