Abstract

We prepared 1-tosyl-2-trifluoroacetylindole - a novel example of an electron-deficient indole with an electrophilic C(3) position. This substance was involved in cyclocondensation with a variety of amidines to propose a new general pathway to 8H-[4,5-b]indolopyrimidines with yield 50-80%. CF3-containing 5H-[3,2-d]indolopyrimidines were unknown before this study.
