Reaction of silyl enol ethers with arenediazonium salts. Part 2. α-Amination of esters was written by Sakakura Toshiyasu;Hara, Masayasu;Tanaka, Masato. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1994.HPLC of Formula: 19432-68-9 This article mentions the following:
Diazonium salts efficiently serve as electrophilic aminating reagents of esters. The reaction of arenediazonium tetrafluoroborates with ketene silyl ketals yielded α-azo or α-hydrazono esters in good to excellent yields under very mild conditions. Hydrogenation of those esters gave α-amino esters quant. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9HPLC of Formula: 19432-68-9).
Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 19432-68-9
