An efficient, transition metal-free visible-light-driven continuous-flow C-3-alkylation of quinoxalin-2(1H)-ones has been demonstrated by employing Katritzky salts as alkylating agents in the presence of eosin-y as a photoredox catalyst and DIPEA as a base at room temperature. The present protocol was accomplished by utilizing abundant and inexpensive alkyl amine (both primary and secondary alkyl) and as well as this a few amino acid feedstocks were converted into their corresponding redox-active pyridinium salts and subsequently into alkyl radicals. A wide variety of C-3-alkylated quinoxalin-2(1H)-ones were synthesized in moderate to high yields. Further this environmentally benign protocol is carried out in a PFA (Perfluoroalkoxy alkane) capillary based micro reactor under blue LED irradiation, enabling excellent yields (72% to 91%) and shorter reaction times (0.81 min) as compared to a batch system (16 h).An efficient, transition metal-free visible-light-driven continuous-flow C-3-alkylation of quinoxalin-2(1H)-ones has been demonstrated enabling excellent yields (72% to 91%) and shorter reaction time (0.81 min) as compared to batch system (16 h). 相似文献

The prevalence of mycotoxigenic Penicillium species in poultry houses of Telangana, India, was studied during 4 seasons between June 2009 and May 2010. Fungi belonging to 13 genera, including Penicillium, comprising 43 species were collected using petri plates. Fourteen Penicillium species demonstrated varying degrees of mycotoxigenicity. Chemical and chromatographic analysis of the different poultry feed samples revealed 8 different mycotoxins with ochratoxin A (OTA) predominating. The mean contamination rate of OTA was 38%. OTA quantities ranged between 5.78 and 6.73 µg/kg?1, 10.13 and 14.23 µg/kg?1, and 12.33 and 15.20 µg/kg?1 in starter, broiler, and layer feeds, respectively. Statistically significant positive correlation between prevalence of Penicillium species and the monsoon, autumn, and spring seasons and negative correlation between prevalence and the autumn, spring, and summer seasons were observed. These findings may serve as risk exposure indicators and contribute toward the initiation of a sustainable control program. 相似文献
