Abstract: Abstract A Bronsted-acid promoted method for the construction of carbon-carbon bonds between α-substituted indolylmethyl electrophiles and ketene dithioacetals is described. This strategy was utilized to access 2,3-disubstituted cyclopenta[b]indoles via formal [3+2] cycloadditions. Readily available indolyl… read more here.
