  Microwave-assisted regioselective synthesis of natural 6-prenylpolyhydroxyisoflavones and their hydrates with hypervalent iodine reagents

  摘要：

  Microwave-assisted oxidative rearrangement of 3'-iodotetraalkoxychalcones with hypervalent iodine such as [hydroxy(tosyloxy)iodo]benzene or [bis(trifluoroacetoxy)iodo] benzene, followed by microwave-mediated hydrolysis and in situ cyclization of the resultant acetals gave 6-iodotrialkoxyisoflavones. Pd(0)-catalyzed coupling reaction of the 6-iodoisoflavones with 2-methyl-3-butyn-2-of under microwave irradiation gave 6-alkynylisoflavones, whose hydrogenation gave the respective hydrates of wighteone, lupisoflavone and derrubone. Wighteone (1a), lupisoflavone (1b) and derrubone (1c) were obtained by dehydration of their respective hydrates under microwave irradiation. (c) 2006 Elsevier Ltd. All rights reserved.

  The palladium-catalyzed coupling reaction of 6-iodoisoflavone, prepared from 3′-iodoacetophenone derivative, with 2-methyl-3-butyn-2-ol gave 6-alkynylisoflavone derivative, which was hydrogenated to give 6-alkylhydroxyisoflavone (luteone hydrate) (2). Dehydration of 2 gave 2′,4′,5,7-tetrahydroxy-6-prenylisoflavone (luteone) (1). Wighteone hydrate (3) was also synthesized from 6-iodotris(benzyloxy)isoflavone in a similar manner. 6-Alkyl-4′5,7-trihydroxy-coumaronochromone (4) was synthesized by oxidative cyclization of 2 with o-chloranil.

  日期：——

  Isoflavones are synthesized in an one-pot reaction by treating the hypervalent iodine(III) reagent, [hydroxy(tosyloxy)iodo]benzene (HTIB, Koser's reagent) with 2'-benzoyloxychalcones in McOH. A combined use of (diacetoxyiodo)benzene (DIB)/p-toluenesulfonic acid (TsOH) is also effective for the same purpose. As an extension of these monomeric reagents, polymer-supported DIB PSDIB, poly[4-(diacetoxy)iodo]styrene}

  通过在 McOH 中用 2'-苯甲酰氧基查耳酮处理高价碘 (III) 试剂 [羟基（甲苯磺酰氧基）碘] 苯（HTIB，Koser 试剂），在一锅法反应中合成异黄酮。(二乙酰氧基碘)苯(DIB)/对甲苯磺酸(TsOH)的组合使用对于相同的目的也是有效的。作为这些单体试剂的扩展，聚合物负载的 DIB PSDIB，聚 [4-(二乙酰氧基)碘]苯乙烯} 与 TsOH 也很有效。后者的优点是易于从反应混合物中分离异黄酮，不会释放 Phi，并且可以重复使用试剂。
