[EN] QUINONE PROTECTED FORMS AND CONJUGATES [FR] FORMES PROTÉGÉES DE QUINONE ET CONJUGUÉS
摘要:
The invention provides protected ortho-quinone compounds comprising a group represented by: Formula (I) where -Ar- is optionally substituted phenylene, -X is selected from -NH2, -OH and -SH, and the protected forms of each, -W- is optionally substituted methylene, such as methylene, and d is a double or single bond, and the salts and solvates thereof
A regioselective biomimetic synthesis of bioactive natural products dunnione and nor-β-lapachone is described. This cascade provides a new strategy of a one-pot process mediated by Lewis acid NbCl5 involving a tandemClaisen rearrangement–cyclization reaction. This procedure was efficient, mild, and easily scalable that avoided using highly hazardous concd H2SO4.
描述了生物活性天然产物地尼酮和去甲β-拉帕酮的区域选择性仿生合成。这种级联反应提供了由路易斯酸NbCl 5介导的一锅过程的新策略,该过程涉及串联的克莱森重排-环化反应。该过程高效,温和且易于扩展,避免了使用高危险浓度的H 2 SO 4的情况。

Abstract From the mature plants, plantlets and cultured cells coexisting with half differentiated plantlets of Streptocarpusdunnii , five unusually prenylated naphthoquinones and one anthraquinone were newly isolated along with both dunnione and 1-hydroxy-2-hydroxymethylanthraquinone, which had already been found in this plant. Furthermore, the structures of four new naphthoquinones, dehydrodunnione
Novel quinones are provided, as well as compositions comprising these novel quinones. Methods of using the novel quinones in treatment of various indications including cancer are also provided.
