A new and efficient epoxide ring opening via poor nucleophiles: indole, p-nitroaniline, borane and O-trimethylsilylhydroxylamine in lithium perchlorate
Abstract Highly regioselective ring opening of 2, 3-dimethyloxirane, 2-epoxyphenylether and allyl (2-epoxymethyl) ether are observed through reactions with poor nucleophiles such as indole, borane, O-trimethylsilylhydroxylamine, p-nitroaniline and sterically hindered tert- butylamine in the presence of 5.0 M lithium perchlorate-Et 2 O solution. These reactions are fast, convenient, with rather high yields and are carried out at ambient temperatures.
