  Using the Pictet–Spengler reactions of tryptophan with aldehydes under acidic conditions at ambient temperature, diastereoisomers of 1,3-disubstituted-1,2,3,4-tetrahydro-β-carbolines could readily be furnished in short time (0.5–4 h) with good to excellent yields (50–98%). Though intrinsically slow in reaction rates, ketone reactions can be accelerated (from days to minutes) using microwaves in open

  使用色氨酸与醛在环境温度下的酸性条件下的Pictet-Spengler反应，可以轻松地在短时间内（0.5–4小时）提供1,3-二取代-1,2,3,4-四氢-β-咔啉的非对映异构体），具有良好至极佳的收率（50–98％）。尽管反应速度本质上很慢，但在开放的容器中使用微波可以加速酮的反应（从几天到几分钟），分离产率高（67-99％），这使这些咔啉成为合成天然和非天然吲哚生物碱的可行反应中间体。 。简要讨论了两种吲哚生物碱的制备，即四氢-β-咔啉二酮哌嗪和四氢-β-咔啉乙内酰脲。

  The diastereoselective synthesis of optically active 1,3‐disubstituted tetrahydro‐β‐carbolines using polar protic Pictet–Spengler cyclization of (S)‐tryptophan methyl ester with five aldehydes RCHO (R═CH3, C2H5, C3H7, C4H9, and C6H5) was studied. As an alternate route, the cyclization of (S)‐tryptophan with the same aldehydes and subsequent methylation of the resulting tetrahydro‐β‐carboline carboxylic

  arboxylic acid derivatives were designed and synthesized, and first evaluated for their anti-TMV, fungicidal and insecticidal activities. Most of these derivatives exhibited good antiviral activity against TMV both in vitro and in vivo. Especially, the activities of compounds 8 and 15 in vivo were higher than that of ribavirin. The compound 8 exhibited more than 70% fungicidal activities against Cercospora

• Structural Basis for β-Carboline Alkaloid Production by the Microbial Homodimeric Enzyme McbB
  作者：Takahiro Mori、Shotaro Hoshino、Shusaku Sahashi、Toshiyuki Wakimoto、Takashi Matsui、Hiroyuki Morita、Ikuro Abe

  The beta-carboline (beta C) alkaloids occur throughout nature and exhibit diverse biological activities. In contrast to beta C alkaloid synthesis in plants, the biosynthesis in microorganisms remains poorly understood. The recently reported McbB from Marinactinospora thermotolerans is a novel enzyme proposed to catalyze the Pictet-Spengler (PS) reaction of L-tryptophan and oxaloacetaldehyde to produce the beta C scaffold of marinacarbolines. In this study, we solved the crystal structure of McbB complexed with L-tryptophan at 2.48 angstrom resolution, which revealed the novel protein folding of McbB and the totally different structure from those of other PS condensation catalyzing enzymes, such as strictosidine synthase and norcoclaurine synthase from plants. Structural analysis and site-directed mutagenesis confirmed that the previously proposed catalytic Glu97 at the active-site center functions as an acid and base catalyst. Remarkably, the structure-based mutants R72A and H87A, with expanded active-site cavities, newly accepted bulky phenylglyoxal as the aldehyde substrate, to produce 1-benzoyl-3-carboxy-beta-carboline.
