has been the cause for considerable research interest, spanning many decades. Herein is reported the synthesis of the structurally closely related compounds denoted as (indol-2-yl)methanamines, in 99 % ee using amino acid starting materials, coupled with a 9-phenyl-9-fluorenyl (Pf) protectinggroup strategy. Furthermore a conformational study of Pf-protected α-amino carbonyl compounds were undertaken
