摘要

As part of an ongoing research program, we sought to develop an efficient general approach to the synthesis of 3-alkoxyindoles 2. 1 Transition metal-catalysed carbenoid insertion of α-diazoketones into alcohols has become a powerful method for the synthesis of α-alkoxyketones and related compounds. 2 We reasoned that 2-carboethoxy-3-diazo-3H-indole 1 could act as a substrate for this reaction as it is isoelectronic with α-diazocarbonyl compounds 3 (Scheme 1) and ...
