Synthesis and Reactions of Azomethines Containing a m-Phenoxyphenyl Group: II. Chemical Transformations >of N-Aryl-m-phenoxyphenylmethanimines and Arylhydrazones of m-Phenoxybenzaldehyde
摘要:
Chemical transformations of N-aryl-m-phenoxyphenylmethanimines and m-phenoxybenzaidehyde arythydrazones were studied by examples of reduction thereof with complex metal hydrides and reactions with dialkyl phosphates and dialkyl phosphites.
Condensation of m-phenoxybenzaldehyde with aromatic amines and hydrazines gave the corresponding Schiff bases and m-phenoxybenzaldehyde arylhydrazones. The products are promising as biologically active substances, polyfunctional additives to rubber compounds, and inhibitors of acid corrosion.

The esterenolate-iminecondensationroute to beta-lactams via an immobilized ester enolate has been achieved for the first time. The key reaction in the synthesis is the cyclization of the resin bound ester dianion and an imine. Traceless cleavage from the T1-triazene linker system yields the desired beta-lactams.

Anhydrous zirconium tetrachloride is found to be an efficient catalyst for the Imino Diels-Alder reactions of N-benzylideneanilines with 3,4-dihydro-2H-pyran and 2,3-dihydrofuran to afford pyrano and furo [3,2-c] quinolines in good yields.

Liquid-phase studies concerning the solid-phase synthesis of monocyclic beta-lactams via the esterenolate imine condensation route have been conducted utilizing triazene esters 1 and 2 as model compounds. Esters were attached to benzylamine resin 6 by a triazene linker employing the respective diazonium salts. Immobilized ester-enolates 8 and 10 were reacted with various imines and imine precursors to give polymer-bound beta-lactams 14 and 17 in different substitution patterns. Traceless cleavage from the triazene linker yields the desired beta-lactams 16 and 19.
