The use of the 2-cyanoethyl group for carboxyl-protection is described. This group was readily introduced by esterification using ethylene cyanohydrin and the deprotection was carried out under mild conditions using tetrabutylammonium fluoride in dimethylformamide-tetrahydrofuran.
介绍了如何使用 2-氰乙基进行羧基保护。该基团很容易通过乙烯氰醇的酯化作用引入,并在二甲基甲酰胺-四氢呋喃中使用四丁基氟化铵在温和的条件下进行脱保护。
