An unexpected product of N-tosyl-7-methoxy-1,3a,4,8b-tetrahydrocyclopenta[b]indole oxidation with potassium permanganate under alkaline conditions was isolated. Along with (2R,3S,3aR,8bS)-N-tosyl-7-methoxy-2,3-dihydroxy-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indole, (3SR,3aRS,8bSR)-N-tosyl-7-methoxy-3-hydroxy-1,2-epoxy-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indole was formed.

The scientific interest in catalytic hydroaminoalkylation reactions of alkenes has vastly increased over the past decade, but these reactions have struggled to become a viable option for general laboratory or industrial use because of reaction times of several days. The titanium-based catalytic system introduced in this work not only reduces the reaction time by several orders of magnitude, into the range of minutes, but the catalyst is also demonstrated to be easily available from common starting materials, at a cost of approximately 1 € per millimole of catalyst. We were also able to formally perform C?H activation of methylamine and achieve coupling to a broad variety of alkenes, through silyl protection of the amine and simple deprotection by water.
