Abstract
|
It is demonstrated that o-quinones, generated by the electrochemically
driven oxidation of the catechols (1a-d) at
physiological pH, are rapidly scavenged by 2-mercaptobenzoxazole
(3) to give related catecholthioethers (4a-d) via an
EC electrochemical mechanism pathway. The electrochemical
syntheses of 4a-d have been successfully performed in
one-pot in ambient conditions and in an undivided cell using
an environmentally friendly method with high atom economy
