使用
3-Isochromanone may be used as starting reagent in the synthesis of of BDPBI (7-bromo-1,4-dihydro-2-phenyl-4,4-bis(4-pyridinylmethyl)2
H-isoquinolin-3-one dihydrochloride).
調製方法
3-Isochromanone is a well-known compound, and several methods for its preparation are described in the chemical literature. For example, it can be prepared by (i) the Baeyer-Villiger oxidation of 2-indanone using hydrogen peroxide in sulphuric acid and acetic anhydride or using 3-chloroperoxybenzoic acid combined with trifluoroacetic acid; (ii) from 2-methoxycarbonylmethylbenzoic acid by (a) treatment with ethyl chloroformate in triethylamine and (b) sodium borohydride; or (iii) from isochroman-3-ol and chromium trioxide. It is also known to prepare 3-isochromanone by the bromination of o-tolylacetic acid with N-bromosuccinimide followed by ring closure by boiling the 2-bromomethylphenylacetic acid so formed with potassium hydroxide in ethanol.
反応性
3-Isochromanone (ICM) is an aromatic lactone. ICM can be synthesised by cationic ring opening polymerisation to produce a polyphenylene containing carboxylic acid molecules in the side chain. the polymerisation of ICM proceeds through the formation of a benzyl cationic intermediate and its successive Friedel-Crafts reactions
[1].
一般的な説明
3-Isochromanone has been reported to be isolated from the fungus
Nigrospora sp. PSU-F12. An improved Knoevenagel condensation of 3-isochromanone with aromatic aldehydes has been achieved by microwave irradiation on solid supports in the presence of various catalysts. Synthesis of 3-isochromanone via Beayer-Villiger rearrangement has been reported.
