  1,9-Bis(N,N-dimethylaminomethyl)dipyrromethanes in the synthesis of porphyrins bearing one or two meso substituents

  摘要：

  A synthesis of 5,15-disubstituted zinc-porphyrins has been developed that employs condensation of a 1,9-bis(N,N-dimethylaminomethyl)dipyrromethane+a dipyrromethane in refluxing ethanol containing zinc acetate followed by oxidation with DDQ. The NN-dimethylaminomethylation of the dipyrromethane was achieved via Eschenmoser's reagent (N,N-dimethylmethyleneammonium iodide) in CH2Cl2 at room temperature. The synthesis is compatible with diverse substituents (e.g., alkyl, aryl, ester, acetal) and enables rapid synthesis of trans-AB-, A(2)-, and A-porphyrins. The synthesis of > 40 zinc porphyrins has been surveyed; 13 zinc porphyrins were isolated in yields of 5-20% without detectable scrambling. (c) 2005 Elsevier Ltd. All rights reserved.

  A method of making a porphyrin is carried out by: (a) condensing (i) a 1,9-bis(N,N-)dialkylaminomethyl)dipyrromethane of Formula II: with (ii) a dipyrromethane to produce a reaction product; then (b) oxidizing the reaction product; and then (c) optionally demetallating said reaction product to produce the porphyrin. The reaction is particularly useful for making substituted porphyrins with a wide range of substituents at the A and/or B (the 5 and/or 15) positions.

  通过以下步骤进行制备卟啉的方法：(a) 缩合(i) 公式II中的1,9-双(N,N-)二烷氨甲基二吡咯甲烷与(ii) 二吡咯甲烷以产生反应产物；然后(b) 氧化反应产物；然后(c) 可选择性地去金属化所述反应产物以产生卟啉。该反应特别适用于制备在A和/或B(第5和/或15)位置具有广泛取代基的取代卟啉。
