Functionalised tetrahydrocarbazoles are accessed through an enantioselective organocatalysed Diels-Alder (D-A) reaction of 3-vinyl-1H-indole with a suitable dienophile in combination with an in situ N-protection. A subsequent diastereospecific ene reaction is then used to transfer chirality from the 10a to the 5 position with rearomatisation of the indolic ring, to give the target tetrahydrocarbazoles in high %ee. The in situ introduction of different N-protecting groups is explored along with their influence on the subsequent ene reactions.
