Synthesis of an Aromatic Ring in Insects

IT is now generally accepted that oxidation products of aromatic compounds are involved in the hardening of the skeletal proteins of insects1. The strong circumstantial evidence that, in blowfly larvæ, tyrosine gives rise to ‘tanning’ phenols2 has recently been substantiated by the finding that injected tyrosine labelled with carbon-14 is converted to N-acetyl-3,4-dihydroxyphenylethy1-amine, the natural tanning agent of Calliphora3.
