(±)-Cryptamides A–D, Four Pairs of Novel Dopamine Enantiomer Trimers from the Periostracum Cicadae

Four pairs of novel dopamine enantiomer trimers, (±)-cryptamides A–D (1–4), and 10 pairs of previously described dopamine enantiomer dimers (5–14) were isolated from the Periostracum cicadae, the cast-off shell of the insect Cryptotympana pustulata. Aside from being pairs of enantiomers, the eight t...

description Four pairs of novel dopamine enantiomer trimers, (±)-cryptamides A–D (1–4), and 10 pairs of previously described dopamine enantiomer dimers (5–14) were isolated from the Periostracum cicadae, the cast-off shell of the insect Cryptotympana pustulata. Aside from being pairs of enantiomers, the eight trimers were also elucidated to be regioisomers, most likely resulting from their mechanism of formation, [4 + 2] cycloaddition. The discovery of dopamine trimers is rarely reported when it comes to natural products derived from insects.
