Dimeric Naphthoquinones, II1) - Simple and Regioselective Synthesis of Naphthoquinol Monoalkyl Ethers via 2,3-DihydronaphthoquinonesOn catalysis of hydrogen chloride or thionyl chloride, 1,4-naphthalenediole (2 a) reacts with primary or secundary alcohols via the tautomeric 2,3-dihydronaphthoquinone (9) to give naphthoquinol monoalkyl ethers 2b - n in high yields. The influence of the substitution pattern on the regioselectivity of the reaction has been investigated.
Notes:
Naphthohydrochinon (2a) reagiert unter Katalyse von Chlorwasserstoff oder Thionylchlorid über das tautomere 2,3-Dihydronaphthochinon (9) mit primären und sekundären Alkoholen in hoher Ausbeute zu den Naphthohydrochinon-monoalkylethern 2b-n. Der Einfluß von Substituenten auf die Regioselektivität der Reaktion wird untersucht.
