An indole of the formula ##STR1## wherein R.sub.5 and R.sub.6 are acetoxy or hydrogen, at least one of R.sub.5 and R.sub.6 being acetoxy, is prepared, in good yield, in a one pot synthesis, without extraction, recrystallization or isolation of intermediate reaction product; A compound of the formula ##STR2## wherein R.sub.1 and R.sub.2 are benzyloxy or hydrogen, provided that at least one of R.sub.1 and R.sub.2 is benzyloxy, is subjected to reductive cyclization followed by acetylation of the resultant reaction product.
公式为##STR1##的吲哚化合物,其中R.sub.5和R.sub.6是乙酰氧基或氢原子,其中至少一个是乙酰氧基,可以在单步合成中高产率地制备,无需提取、重结晶或分离中间反应产物;公式为##STR2##的化合物,其中R.sub.1和R.sub.2是苄氧基或氢原子,但至少一个是苄氧基,经过还原环化反应后,对所得到的反应产物进行乙酰化处理。
