  3-Methyl-4-phenylpyrrole from the Ants Anochetus kempfi and Anochetus mayri

  摘要：

  The cephalic extracts of the ant Anochetus kempfi were found to contain 2,5-dimethyl-3-isoamylpyrazine (1) and 3-methyl-4-phenylpyrrole (2). The structures of these compounds were established from their spectral data and by comparison with synthetic samples. This is the first report of a phenylpyrrole found in an insect and only the third report of a pyrrole from ants.

  An unusual dehalogenation in the Suzuki coupling of 4-bromopyrrole-2-carboxylates

  摘要：

  An unusual dehalogenation of 4-bromopyrrole-2-carboxylates under Suzuki coupling conditions has been observed. This dehalogenation can be suppressed by protection of the pyrrole nitrogen. Using a BOC protecting group, not only is dehalogenation suppressed, but the protecting group is also removed under the reaction conditions. (C) 2002 Elsevier Science Ltd. All rights reserved.

  A simple one-pot procedure for the production of 2-carboxylpyrroles with 4-alkyl, 5-alkyl, 4-aryl, 4-aryl-5-alkyl, or 3,4-diaryl substitution patterns is presented. The procedure involves the titanium-catalyzed multicomponent coupling of alkynes, primary amines and isonitriles to give 1,3-diimines in situ; the multicomponent product is then treated with the ethyl ester of glycine hydrochloride to give

  提出了一种简单的一锅法，用于生产具有4-烷基，5-烷基，4-芳基，4-芳基-5-烷基或3,4-二芳基取代模式的2-羧基吡咯。该方法涉及炔烃，伯胺和异腈的钛催化多组分偶合，从而原位生成1,3-二亚胺。然后将多组分产物用盐酸甘氨酸乙酯处理，得到NH-吡咯。该反应可以用中和的甘氨酸酯或以DBU为碱的盐酸盐进行。在一个锅法中，基于起始炔烃的吡咯收率在25％到65％之间变化，并且在大多数情况下，仅观察到产物的一种区域异构体。此外，提出反应的区域选择性是在用甘氨酸乙酯相对较快的氨基转移后速率决定闭环的结果。

  biological evaluation of novel (E)-3-(2-(N-phenylcarbamoyl)-vinyl)pyrrole-2-carboxylic acids bearing alkyl, acyl, alkoxy, phenyl, and halo substituents at the 4- and 5-positions of the pyrrole ring are reported. These compounds were studied for their in vitro affinity at the strychnine-insensitive glycine-binding site of the N-methyl-D-aspartate (NMDA) receptor complex.
