对于化合物13(方案4)和化合物18(表3,条目6),报告的产率不正确。正确的收率是81%和88%。溶剂峰已经从除去1 1 H NMR谱报告为化合物13,图9a,图9b,图9c,图9d,14,9f中,9克,9I,9J,9K,图6a,图6b,6H,6J,6K,6N,17,18和19。找到了原始的FID,并对光谱进行了重新处理,并已在通过此更正提交的修订的《支持信息》中替换了上述化合物。光谱编辑不会影响已发表论文的任何结论。根据修订后的光谱计算出的纯度如下:13(98%),9a(97%),9b(99%),9c(99%),9d(99%),14(98%),9f(94%),9g(88%),9i(99%),9j(99%),9k(99%),6a(98%),6b(97%),6h(91%),6j(99%),6k(97%),6n(97%),17(97%),18(98%)和19(95%)。修订后的支持信息,包括
(1-nosyl-5-nitroindol-3-yl)methylesters as a novel protective group for carboxylicacid is fully demonstrated. The novel protective group is stable under a broad range of conditions and can easily be deprotected under the mild conditions used for removal of the nosyl (Ns) group. It is orthogonal to the existing protective groups for carboxylicacids such as t-butyl and allyl esters.
