Organo-Photoredox Catalyzed Oxidative Dehydrogenation of N-Heterocycles

We report here for the first time the catalytic oxidative dehydrogenation of N-heterocycles by a visible-light organo-photoredox catalyst with low catalyst loading (0.1?1 mol %). The reaction proceeds efficiently under base- and additive-free conditions with ambient air at room temperature. The utility of this benign approach is demonstrated by the synthesis of various pharmaceutically relevant N-heteroarenes such as quinoline, quinoxaline, quinazoline, acridine, and indole.

Analysis of alpha- and beta-carbolines in mainstream smoke of reference cigarettes by gas chromatography-mass spectrometry

The levels of 2-amino-9H-pyrido[2,3-b]indole (AalphaC or 2-amino-alpha-carboline), 2-amino-3-methyl-9H-pyrido[2,3-b]indole (MeAalphaC or 2-amino-3-methyl-alpha-carboline), 9H-pyrido[3,4-b]indole (norharman), and 1-methyl-pyrido[3,4-b]indole (harman) have been determined in the mainstream smoke condensate from three reference cigarettes, namely Kentucky reference 1R5F, Kentucky reference 2R4F, and CORESTA CM4. The amino-alpha-carbolines, and norharman and harman (beta-carbolines) can be classified as heterocyclic aromatic amines (HAAs) and are listed as biologically active agents in the mainstream smoke of cigarettes. For the analysis, the mainstream smoke condensate from cigarettes was collected on a filter pad, the analytes were isolated using solid-phase extraction (SPE), and quantified without derivatization on a GC-MS. Total amounts of carbolines found in the condensate increased from ultralight 1R5F to full-flavor CM4 cigarettes. The level of harman was about 250 ng/cigarette for the 1R5F cigarette and about 1025 ng/cigarette for the CM4 cigarette. Norharman was typically three times more abundant than harman. The AalphaC was found at about 10 times lower level compared to harman, and MeAalphaC was about 50 times lower than harman. The use of reference cigarettes can provide a common measure for laboratories to assess carboline amounts among cigarette brands.

Cloning and expression of naphthalene dioxygenase genes from Comamonas sp. MQ for indigoids production

The naphthalene dioxygenase (NDO) genes were cloned from Comamonas sp. MQ and successfully expressed in Escherichia coli BL21 (DE3) (designated as ND-IND). The whole cells of recombinant strain ND-IND possessed relatively high transformation efficiency towards indole and most indole derivatives. According to the UV-vis and HPLC-MS analyses, the major products derived from the indoles could be indigo with different substituent groups. Furthermore, strain ND-IND was able to produce 205 mg/l indigo from 300 mg/l indole with a specific production rate of 8.4 mg/(g dry cell weight h). The effects of phenol, pyridine and quinoline on indigo production were determined, which indicated that phenol and pyridine had little inhibition on indigo production while quinoline would result in a 32% decrease in indigo yield. The present study proposed the potential application of recombinant strain ND-IND in indigoid pigments production, and offered the promise of applying strain ND-IND for the production of indigo using indole-containing wastewater as the raw materials.

Iron phthalocyanine as an efficient and versatile catalyst for N-alkylation of heterocyclic amines with alcohols: One-pot synthesis of 2-substituted benzimidazoles, benzothiazoles and benzoxazoles

An efficient and versatile iron phthalocyanine catalyzed method has been developed for N-alkylation of various amines with alcohols. Readily available alcohols were used as alkylating agents for direct N-alkylation of aminobenzothiazoles, aminopyridines and aminopyrimidines. N-Alkylation of ortho-substituted anilines (-NH2, -SH and -OH) led to the synthesis of 2-substituted benzimidazoles, benzothiazoles and benzoxazoles in one pot.

Well-Defined Noble Metal Single Sites in Zeolites as an Alternative to Catalysis by Insoluble Metal Salts

Insoluble precious metal chlorides in polymeric form (i.e., PtCl2, PdCl2, AuCl, RhCl3) are commonly used as catalysts for a plethora of organic reactions in solution. Here we show that only the minor soluble fraction of these precious metal chlorides (typically 5-30%) is catalytically active for the hydroamination, hydroalkoxylation, hydrosilylation, and cycloisomerization of alkynes and alkenes, and that the resting insoluble metal is catalytically useless. To circumvent this waste of precious metal and follow a rational design, we generate here well-dispersed Pt(II) and Pd(II) single sites on zeolite Y, with an exquisite control of the Lewis acidity, to catalyze different hydroaddition reactions to alkynes and alkenes with up to 104 catalytic cycles (at least 2 orders of magnitude superior to precious metal chlorides) and with high isolated yields (82-99%, >15 examples).
