An efficient palladium-catalyzed reaction of N-propargyl oxazolidines for the construction of 4-substituted isoquinolines under microwave irradiation is developed. This transformation proceeds through a sequential palladium-catalyzed reductive cyclization/ring-opening/aromatization cascade via C-O and C-N bond cleavages of the oxazolidine ring. The practical value of this method has also been explored by conducting a millimole-scale reaction, as well as by transforming the isoquinoline into a key intermediate for the synthesis of a lamellarin analogue.

A concise and efficient three-step strategy for the synthesis of functionalized 1,2,3,4-tetrahydroisoquinolines based on an intramolecular Buchwald-Hartwig α-arylation of β-amino esters is described. The synthesis presented is operationally simple and is amenable for the synthesis of a number of analogues. Georg Thieme Verlag Stuttgart · New York.
Synthesis and antitumor evaluation of a novel class of 4-substituted-1,4- dihydroisoquinolin-3-ones
Ma, Ting,Chen, Wenteng,Zhang, Guolin,Yu, Yongping
scheme or table, p. 488 - 490 (2010/09/05)
An efficient method for the solution-phase parallel synthesis of 4-substituted-1,4-dihydroisoquinolin-3-ones is developed. The isoquinolinones were constructed employing an intramolecular Heck reaction, providing full regio- and stereoselectivity. Most of
