摘要

Figure 1 shows a perspective drawing of the final X-ray model of this indole. The bond lengths and angles agree well with generally accepted values, though the C (6)-C-(7)-C (8) angle is rather small due to the electron-withdrawing effect of the sulfamoyl group at C (6). 6 The indole skeleton of 7b is nearly planar (maximum deviation 0.017 A) but exhibits a slight folding about the ring junction. The N-methylsulfamoyl group is oriented to place the ...
