This application relates to para-quinol derivatives, such as analogues of manumycins, aranorosins and gymnastatins. This application also relates to methods of synthesizing and using the para-quinol derivatives. In one embodiment of the invention a compound having the chemical structure (I) is provided wherein X
1
and X
2
are carbon atoms either joined by double bond or joined by a single bond and comprising constituents of an epoxide ring or a hydroxyethylene moiety; X
3
and X
4
are carbon atoms either joined by double bond or joined by a single bond and comprising constituents of an epoxide ring; R
1
is selected from the group consisting of branched alkyl chains, unbranched alkyl chains, cycloalkyl groups, aromatic groups, alcohols, ethers, amines, and substituted or unsubstituted ureas, esters, aldehydes and carboxylic acids; and R
2
is selected from the group consisting of H, OH and NHR
3
wherein R
3
is a nitrogen protecting group. In a particular embodiment of the invention R
1
is a polyunsaturated carbon chain as found in biologically active manumycins. The applicant's synthetic method may involve diasteroselective formation of a spirolactone in an oxidative spiroannulation process using tyrosine or a tyrosine derivative having a chiral centre as a starting material.
本申请涉及对位喹啉衍生物,例如曼纽霉素、阿拉诺罗辛和体操霉素的类似物。本申请还涉及合成和使用对位喹啉衍生物的方法。在发明的一个实施例中,提供了具有化学结构(I)的化合物,其中X1和X2是由双键连接或单键连接的碳原子,并包括环氧环或羟基乙烯基的组分;X3和X4是由双键连接或单键连接的碳原子,并包括环氧环的组分;R1选自支链烷基链,直链烷基链,环烷基团,芳香族团,醇,醚,胺和取代或未取代的脲、酯、醛和羧酸;R2选自H,OH和NHR3,其中R3是氮保护基。在发明的一个特定实施例中,R1是生物活性曼纽霉素中发现的多不饱和碳链。申请人的合成方法可能涉及使用酪氨酸或手性中心的酪氨酸衍生物作为起始材料,在氧化螺环化过程中二面体选择性地形成螺内酯。
