The present invention provides compounds useful in the synthesis of biologically active compounds, and processes for their production, the compounds having the formula:
wherein: R1 and R2 are, independently, selected from H; C1-C12 alkyl or C1-C6 perfluorinated alkyl; X represents a leaving group; A is 0 or S; m is an integer from 1 to 3, preferably 2; R3, R4, R5, and R6 are independently selected from H, halogen, —NO2, alkyl, alkoxy, C1-C6 perfluorinated alkyl, OH or the C1-C4 esters or alkyl ethers thereof, —CN, —O—R1, —O—Ar, —S—R1, —S—Ar, —SO—R1, —SO—Ar, —SO2—R1, —SO2—Ar, —CO—R1, —CO—Ar, —CO2—R1, or —CO2—Ar; and Y is selected from a) the moiety:
wherein R7 and R8 are independently selected from the group of H, C1-C6 alkyl, or phenyl; or b) an optionally substituted five-, six- or seven-membered saturated, unsaturated or partially unsaturated heterocycle or bicyclic heterocycle containing up to two heteroatoms selected from the group consisting of —O—, —NH—, —N(C1C4 alkyl)—, —N═, and —S(O)n—.
本发明提供了在合成生物活性化合物方面有用的化合物以及它们的制备方法,其中化合物的式子为:其中:R1和R2分别选自H;C1-C12烷基或C1-C6全氟烷基;X代表离去基团;A为0或S;m是1到3的整数,优选为2;R3、R4、R5和R6独立地选自H、卤素、—NO2、烷基、烷氧基、C1-C6全氟烷基、OH或其C1-C4酯或烷基醚、—CN、—O—R1、—O—Ar、—S—R1、—S—Ar、—SO—R1、—SO—Ar、—SO2—R1、—SO2—Ar、—CO—R1、—CO—Ar、—CO2—R1或—CO2—Ar;Y选自a)基团:其中R7和R8独立地选自H、C1-C6烷基或苯基;或b)一个可选取代的含有最多两个杂原子(选自—O—、—NH—、—N(C1-C4烷基)—、—N═和—S(O)n—)的五元、六元或七元饱和、不饱和或部分不饱和杂环或双环杂环。
