Substituted .gamma.-butyrolactones. Part 37: reactions of (arylmethylene)furandiones with nucleophiles. A novel approach to the cyclolignan lactone skeleton
A series of new, N-substituted azapodophyllotoxin derivatives were synthesized via a three-component reaction of an aldehyde, an enaminone and tetronic acid in glacial acetic acid, undermicrowaveirradiation, without a catalyst. This new protocol has the advantages of shorter time, higher yields, lower cost and broader substrate scope, as well as easier operation.
通过醛、烯胺酮和特罗尼酸在冰醋酸中,在微波辐射下,无催化剂的三组分反应,合成了一系列新型 N 取代的氮杂鬼臼毒素衍生物。这种新协议具有时间更短、产量更高、成本更低、基材范围更广、操作更简单等优点。

By Knoevenagel condensation and by three-component condensation 3-arylmethylenetetrahydrofuran-2,4-diones and previously unknown 8,11-dihydro-11-arylbenzo[f]furo[3,4-b]quinolin-10(7H)-ones were respectively synthesized. The luminescent spectra and nonlinear-optical characteristics of compounds obtained were investigated.
