A new procedure for protecting the amide, lactam, urea, and carbamate NH group with a triphenylmethyl (Tr) group is described. The utility of this method is illustrated with molecules that contain other functional groups. A mild deprotection using trifluoroacetic acid makes this a useful method for attaching amide groups on resin for combinatorial synthesis.
描述了用三苯甲基(Tr)基保护酰胺,内酰胺,尿素和氨基甲酸酯NH基的新方法。包含其他官能团的分子说明了该方法的实用性。使用三氟乙酸的温和脱保护使其成为在组合合成树脂上连接酰胺基的有用方法。
