Synthesis of C3-Symmetric Macrocyclic Triimines from Monomers Having Boc-protected Amine and Formyl Group

A concise access to C3-symmetric macrocyclic triimines was developed. When biphenyls having a formyl group on one phenyl group and an NHBoc group on the other phenyl group were treated with an excess amount of concentrated HCl in 1,4-dioxane, the detachment of the Boc group followed by a trimerization reaction via imine formation proceeded smoothly to afford C3-symmetric imine-linked macrocycles in good chemical yields.

Spirodienones part 8. The direct preparation of spirodioxole- and spirobenzoxazole-cyclohexadienones by the oxidation of 4-aryloxyanilines

Oxidation of 4(2-hydroxyphenoxy)anilines 1b to 1d with active manganese dioxide leads directly to quinone mono-ketals 2b to 2d in reasonable yield. Similar reaction of 4 (2-sulfonamidophenoxy)anilines 9a, 9b provides an efficient synthesis spirobenzoxazolecyclohexadienones 10a and 10b but treatment with manganese dioxide of alcohol 3 and oxime 6 gives respectively azobenzene 4 and terphenyl 7 rather than spirodienones.
