In preliminary studies we found 4-nitrophenyl sulfamate esters to be competent coupling partners with our tricyclic amines. However, synthesis of the 4-nitrophenyl sulfamate ester from the tricyclic amine is complicated by undesired homodimeric sulfamide formation; see ref. 24

See the ESI for details. In the intramolecular Rh-catalyzed C-H amination, secondary ethereal C-H bonds react preferentially over both secondary benzylic and tertiary C-H bonds, see ref. 19g tert-Butylbenzenesulfonyl protective group was utilized to increase solubility of tricycle (-)- 18 in isopropyl acetate, the optimal solvent for the rhodium-catalyzed C-H amination For key references on oxidation of sulfamides, see

The acid-mediated rearrangement of meso-chimonanthine under similar conditions has previously been described by Overman and co-workers, see: ref. 4i. For the acid mediated rearrangement of a related natural product containing the meso-chimonanthine substructure, see

Although the specific decomposition products could not be fully identified, mass spectral analysis indicated the presence of oxindole related byproducts Attempts at the acid-mediated rearrangement of both (-)-calycanthidine (1) and (+)-DMMC (3) led to exclusive fragmentation of the C3a-C3a′ bond as evidenced by the isolation of N-methyltryptamine. A similar result has been observed in the attempted acid-mediated rearrangement of (±)-folicanthine, see ref. 4h
