An Efficient Synthesis of N-Cyclopropylanilines by a Smiles Rearrangement
摘要:
Treatment of 2-chloro-N-cyclopropylacetamide with phenols gave the corresponding 2-aryloxy-N-cyclopropylacetamides, which on treatment with a base gave the corresponding N-cyclopropylanilines.

Several (3 + 2) cycloaddition reactions catalyzed by dirhodium(II) complexes between N-arylaminocyclopropane and alkenes derivative have been developed. Preliminary mechanism studies suggest that dirhodium(II) complexes may decrease the bond-dissociation energy (BDE) of the N–H bond of N-arylaminocyclopropanes for N–H bond activation, thus facilitating the formation of N-centered radicals by loss of
We report here a regiospecific [3 + 2] annulation between aminocyclopropanes and various functionalized alkynes enabled by a P/N-heteroleptic Cu(I) photosensitizer under photoredox catalysis conditions. Thus, a divergent construction of 3-aminocyclopentene derivatives including methylsulfonyl-, arylsulfonyl-, chloro-, ester-, and trifluoromethyl-functionalized aminocyclopentenes could be achieved with

cyclopropylanilines is reported. This cascade radical reaction constructs two new C–C bonds and two rings to afford 3-aminotetrahydro-1H-carbazols with high atom and step economy. The mechanism is rationalized as involving sequential distonic radical cation formation/isocyanide insertion/5-exo-trig cyclization/intramolecular iminium ion addition/tautomerization.
