Pd0-catalyzed cyclization reaction of aryl or alk-1-enyl halides with 1,2-dienyl ketones: a general and efficient synthesis of polysubstituted furans
Abstract
Under catalysis by Pd0 and Ag2CO3, the reaction of 1,2-allenyl ketones and organic halides in PhMe using Et3N as the base provides a new general access to polysubstituted furans with good to excellent yields.
