Two-Step Access to β-Substituted o-Hydroxyphenyl Ethyl Ketones from 4-Chromanone and its Application in Preparation of a Silica-Supported Cobalt(II) Salen Complex

The o-hydroxyphenyl ethyl ketone skeleton is prevalent in many biologically active natural products and active pharmaceutical ingredients. Herein, a two-step protocol has been developed for synthesis of various β-substituted o-hydroxyphenyl ethyl ketones.

A novel oxidative intramolecular [4+2]cycloaddition of silylene-protected dihydroxystyrene derivatives leading to peri-hydroxy polyclic aromatic compounds: A synthesis of the ABCD ring system of fredericamycin A

Heating of the silylene protected dihydroxystyrene generated from the o-hydroxyacetophenone (3a) at 130-150°C for 15-48 h in a sealed tube gave intramolecular [4+2]cycloaddition products (5 and 6). The addition of chloranil to the reaction mixture brought

A NOVEL INTRAMOLECULAR CYCLOADDITION OF SILYENE PROTECTING DIHYDROXYSTYRENE DERIVATIVES: A VERSATILE SYNTHESIS OF LINEARLY CONDENSED PERI-HYDROXY AROMATIC COMPOUNDS

The firts example of an intramolecular cycloaddition of the silylene protecting dihydroxystyrene derivatives leading to linearly condensed peri-hydroxy aromatic compounds (6a-c) is desribed.
