Furan and 2-hydroxymethylfuran were reacted under Lewis acidic oligomeric precursors, for a subsequent Lewis acid catalysed cyclisation to afford the furan based calixarenes, i.e.cyclic tetramer2a, and small quantities of the cyclic pentamer2b, hexamer 2c and octamer2d.
呋喃和 2- 羟甲基呋喃在路易斯酸低聚物前体下发生反应,随后在路易斯酸催化下发生环化反应,得到了以呋喃为基础的钙钛矿,即环状四聚体 2a,以及少量环状五聚体 2b、六聚体 2c 和八聚体 2d。
