[reaction: see text] The reaction outcome of 2-azidoethanol and aliphatic aldehyde is found to be dependent on the catalyst and the structure of the azido alcohol. Under the catalysis of Cu(II) triflate, the corresponding acetal is obtained. A similar reaction between 2-aryl-2-azidoethanol and aldehyde catalyzed by BF3 yields a mixture of 3-oxazoline and 2-oxazoline. The latter reaction has been used
Highly α-position regioselective ring-opening of epoxides catalyzed by halohydrin dehalogenase from <i>Ilumatobacter coccineus</i>: a biocatalytic approach to 2-azido-2-aryl-1-ols
Halohydrindehalogenases are usually recognized as strict β-position regioselective enzymes in the nucleophile-mediated ring-opening of epoxides. Here we found the HheG from Ilumatobacter coccineus exhibited excellent α-position regioselectivity in the azide-mediated ring-opening of styrene oxide derivatives 1a–1k, producing the corresponding 2-azido-2-aryl-1-ols 2a–2k with the yields up to 96%.
