  Processing of o-Halobenzoates by Toluene Dioxygenase. The Role of the Alkoxy Functionality in the Regioselectivity of the Enzymatic Dihydroxylation Reaction

  摘要：

  In order to investigate the relationship between the size of a substituent on the aromatic substrate and its directing effect on the dihydroxylation, a series of 2-halobenzoates was synthesized and subjected to metabolism by toluene dioxygenase in preparative-scale fermentation cultures of Escherichia coli JM109 (pDTG601A). Larger ester substituents were shown to have a greater directing effect on the dihydroxylation reaction. Furthermore, significant increases in regioselectivity were observed using propargyl substituents, relative to the use of any other ester substituent. The selectivity and the product ratios are reported for o-fluoro-, o-chloro-, o-bromo-, and o-iodobenzoate esters (methyl, ethyl, n-propyl, allyl, and propargyl). Experimental and spectral data, as well as absolute stereochemistry, are provided for all new compounds.

  A highly active, air-stable, and versatile procedure for Buchwald-Hartwig and Sharpless-Meldal C-N bond formation is reported. Under nearly solvent-free conditions using copper(II) acetate and 2-phenyl-2-(4-phenyl-1H-1,2,3-triazol-1-yl)ethanol, a variety of N-heterocycles and various cyclic and noncyclic secondary amines were arylated to form N-aryl compounds in moderate to excellent yields. This methodology also provides rapid access to diverse 1,4-disubstituted 1,2,3-triazoles in good to excellent yields. All reactions are performed in short times under air.
