Abstract
All the possible stereoisomers of N‐(2′‐methylbutyl)pyrrolidine 1 and N‐(2′‐methylbutyl)‐2‐methylpyrrolidine 2, which have the characteristic roast odour of seafood, were synthesized. As a result of odour evaluation of all the isomers, we found that each isomer has a different and characteristic odour. Copyright © 2003 John Wiley & Sons, Ltd.
