Selective alkoxycarbonylation of 2,3-dichloropyridines
Bessard, Yves,Roduit, Jean Paul
, p. 393 - 404 (1999)
2,3-Dichloropyridines undergo a motto- or a dicarbonylation in the presence of carbon monoxide, an alcohol and a palladium catalyst, affording selectively either alkyl 3-chloropicolinates, or dialkyl pyridine-2,3- dicarboxylates in good yields, depending on the reaction conditions.
A New Synthesis of Lysergic Acid
Hendrickson, James B.,Wang, Jian
, p. 3 - 5 (2007/10/03)
(Equation presented) (±)-Lysergic acid (1) has been synthesized via an economical 8-step route from 4-bromoindole and isocinchomeronic acid without the need to protect the indole during the synthesis. Initial efforts to form the simpler 3-acylindole derivatives first and then cyclize these were unsuccessful in the cyclization step.
