2,2-dialkylacetaldehydes with electron-rich 2-naphthols in presence of p-TSA under closed-vessel solvent-free microwave irradiation conditions resulted in formation of corresponding dihydronaphtho[2,1-b]furans in good to excellent yields. In several cases, small amounts of 14-alkyl-14H-dibenzo[a,j]xanthenes were also formed.
2,2-二烷基乙醛与p -TSA存在下的富电子2-萘在密闭容器无溶剂微波辐射条件下反应,可形成相应的二氢萘[2,1- b ]呋喃,收率高至优异。在几种情况下,还形成了少量的14-烷基-14 H-二苯并[ a,j ]蒽。
