described for the synthesis of piperidone 13, a precursor for 4-isothiocyanatopiperidine 2. NaBH4 or LiAlH4 reduction of 4-(2-benzo[b]thienyl)-4-hydroxycyclohexanone 18 and 4-(2-benzo[b]thienyl)-4-(piperidino)cyclohexanone oxime 35 gives the corresponding cis-diol 21 and cis-cyclohexane-1,4-diamine 36 as the major isomers which have been investigated as precursors to the cyclohexane ring isothiocyanates
同分异构的异硫氰酸酯衍生物2 - 7强效的多巴胺再摄取(DA)抑制剂1- [1-(2-苯并[的b ]噻吩基)环己基]哌啶(BTCP 1)已被合成作为此网站潜在的不可逆配体。的NaNO 2 -CF 3 CO 2 H,条件温和的程序为苯并[硝化b ]噻吩基的环1为芳基的路线异硫氰酸酯5 - 7。描述了利用3,3-乙烯二氧基戊烷-1,5-二醇二甲磺酸酯的新方法用于合成哌啶酮13,哌啶酮13是4-异硫氰酸根合哌啶的前体2。加入NaBH 4或的LiAlH 4还原4-(2-苯并[ b ]噻吩基)-4-羟基环己酮18和4-(2-苯并[ b ]噻吩基)-4-(哌啶子基)环己酮肟35,得到相应的顺式-二醇21和CIS -环己烷-1,4-二胺36作为已经被研究作为前体到环己烷环异硫氰酸酯的主要的异构体3和4。比较了通往3和4的替代路线,并研究了其立体化学结果。
