  Synthesis of substrate analogs of methyltransferases in the vitamin B12 biosynthetic pathway and characterization of their enzymatic products

  摘要：

  The specificity toward substrate analogs of the first two methyltransferases in the vitamin B-12 biosynthetic pathway was probed with 15 synthetic porphyrinogens. Several novel methylated chlorins and isobacteriochlorins were isolated and characterized, suggesting the same methylation sequence C-2 > C-7 > C-20 as for the natural substrate, uro'gen III. The results allow us to narrow down possible structural requirements concerning substrate recognition by the methyltransferase enzymes. (c) 2006 Elsevier Ltd. All rights reserved.

  α-Acetoxymethylpyrroles couple with α-free pyrroles in presence of Montmorillonite clay to form unsymmetrical pyrromethanes in excellent yields. Symmetrical pyrromethanes were also prepared in a similar manner by clay catalysed self-condensation of α-acetoxymethylpyrroles.

  在蒙脱石粘土的存在下，α-乙酰氧基甲基吡咯与无α吡咯偶联，以极高的收率形成不对称的吡咯甲烷。还通过粘土催化α-乙酰氧基甲基吡咯的自缩合以类似方式制备对称的吡咯甲烷。
