, p. 6903 - 6908 (2019/09/30)
The competition between an unprecedented reductive chlorination and the Pummerer reaction was studied and applied to the synthesis of benzofused oxygen heterocycles including 3-aminochromanes and in the intramolecular chlorination of activated aromatic ri

The title compound readily deprotonates and reacts with appropriate electrophiles to form derivatives which upon subsequent treatment with Lewis acids undergo ring closure to afford fused aromatics.

The (+)-cis-chromanochromanones (2) and (3), respresenting the basic ring system of the natural insecticide rotenone, have been synthesised by a general procedure; the key step is 4-aroylation of the 4-(phenyl-sulphonyl)chromans (7; Z=SO2Ph).
