Wild type, mutant, and recombinant bacterial strains capable of oxidizing aromatic hydrocarbons were screened for their ability to oxidize anisole, and phenetole. Toluene induced cells of Pseudomonas putida F39/D transformed anisole to a compound tentatively identified as cis-1,2-dihydroxy-3-methoxycyclohexa-3,5-diene, 2-methoxyphenol, catechol, and trace amounts of phenol while phenetole was converted primarily to cis-1,2-dihydroxy-3-ethoxycyclohexa-3,5-diene and 2-ethoxyphenol. Induced cells of Pseudomonas sp. NCIB 9816/11 and Beijerinckia sp. B8/36 transformed anisole to phenol, and phenetole to phenol and ethenyloxybenzene. Toluene induced cells of P. putida BG1 converted anisole to phenol but did not oxidize phenetole. In contrast, toluene induced cells of P. mendocina KRl, which oxidize toluene via monooxygenation at the para position, transformed anisole to 4-methoxyphenol, and phenetole to 2-, 3-and 4-ethoxyphenol. The involvement of toluene and naphthalene dioxygenases in the reactions catalyzed by strains F39/D and NCIB 9816/11, respectively, was confirmed with recombinant E. coli strains expressing the cloned dioxygenase genes. The results show that the oxygenases from different Pseudomonas strains oxidize anisole and phenetole to different hydroxylated products.

由B(C醚取代的醇与羰基化合物的化学选择性脱氧6 ˚F 5)3 -催化还原(HME 2 SICH 2)2 †
摘要:
使用(HMe 2 SiCH 2)2作为还原剂,开发了B(C 6 F 5)3催化的醚取代的醇和羰基化合物的脱氧反应。这种独特的试剂显示出优于传统的以硅为中心的氢硅烷的独特优势,可高收率地提供相应的烷烃,并对醚,芳基卤化物和烯烃具有良好的耐受性。对照实验表明(HMe 2 SiCH 2)2可能以分子内Si / O活化方式促进该方法。
Anion nucleophilicity in ionic liquids: a comparison with traditional molecular solvents of different polarity
摘要:
The nucleophilic reactivity of a homogeneous series of anions (halides, pseudohalides and organic anions) in the ionic liquids [hexmim] [ClO4] and [hexmim] [PF6] has been measured in their reaction with n-alkyl methanesulfonates, and compared with that found in traditional molecular solvents of different polarity, that is, chlorobenzene, DMSO, and MeOH.

The present invention provides a novel heterocyclic compound. A heterocyclic compound represented by general formula (1) wherein, R1 and R2, each independently represent hydrogen; a phenyl lower alkyl group that may have a substituent(s) selected from the group consisting of a lower alkyl group and the like on a benzene ring and/or a lower alkyl group; or a cyclo C3-C8 alkyl lower alkyl group; or the like; R3 represents a lower alkynyl group or the like; R4 represents a phenyl group that may have a substituent(s) selected from the group consisting of a 1,3,4-oxadiazolyl group that may have e.g., halogen or a heterocyclic group selected from pyridyl group and the like; the heterocyclic group may have at least one substituent(s) selected from a lower alkoxy group and the like or a salt thereof.
Direct C-S bond coupling is an attractive way to construct aryl sulfur ether, a building block for a variety of biological active molecules. Herein, we disclose an effective model for regioselective thiolation of the aromatic C-Hbond by thiolactivation instead of arene activation. Strikingly, this method has been applied into anisole derivatives that are not available in the arene activation approach
