Aromatisation in adducts of alpha-terpinene: Influence of hindered internal rotations
(Science Reviews 2000 Ltd, 2011)
Each adduct of alpha-terpinene with p-quinone and 1,4-naphthoquinone in Ac(2)O/Et(3)N at 180 C gives two aromatic products, one of which had a distinctive smell formed by the loss of an ethylene group. Here, we report the ...
