Reduction of a range of benzo-fused cyclic sulfonamides has been accomplished using low-valent titanium. This operationally simple method generates the corresponding aryl-substituted cyclic amines, typically, with good conversion. Notably, unlike our previous Li-NH3-based method, loss of heteroatom-based substituents (X) on the aromatic ring does not readily occur, and the robustness of this method
使用低价钛已经实现了一系列苯并稠合的环状磺酰胺的还原。该操作简单的方法通常以良好的转化率产生相应的芳基取代的环胺。值得注意的是,与我们以前的基于Li-NH 3的方法不同,芳环上不易发生杂原子基取代基(X)的损失,并且该方法的健壮性通过Sceletium生物碱膜的合成得到了证明。
