Also of great importance for the scent profile is indole, the odour of which resembles that of human faeces. However, at high dilution it develops a powerful floral component with unusually interesting scent properties. In 1962, Edouard Demole and Edgar Lederer achieved the critical isolation and structure determination of a third characteristically scented component of jasmine absolue, namely methyl (Z)-(3R,7R)-jasmonate and methyl (Z)-(3R,7S)-jasmonate (Fig. 3.21).
