A new route to the regioisomeric 2-alkylnaphtho[2,1-b]- and 2-alkylnaphtho[1,2-b]furans via acid-catalyzed cyclization of the corresponding 2-naphthyloxyalkanals under mild conditions over Amberlyst 15 resin has been described. The 2-naphthyloxyalkanals were obtained by palladium-catalyzed reduction of 2-naphthyloxyalkanoyl chlorides.
已经描述了在温和的条件下在琥珀色15树脂上通过酸催化相应的2-萘氧基烷醛的环化反应合成区域异构的2-烷基萘[2,1-b]-和2-烷基萘[1,2-b]呋喃的新途径。 。通过钯催化还原2-萘氧基链烷酰氯获得2-萘氧基链烷醛。
