ChemInform Abstract: One-Pot Dichotomous Construction of Inside-Azayohimban and Pro-Azayohimban Systems via an Enantioselective Organocatalytic Cascade; Their Use as a Model to Probe the (Aza-)Indole Local Solvent Environment.
Five contiguous stereocenters containing inside-azayohimban (X) and pro-azayohimban (IVa) as well as derivatives thereof are prepared and their photochemical properties are examined.
