4-Phenyl tetrahydroisoquinolines as dual norepinephrine and dopamine reuptake inhibitors
摘要:
Novel 4-phenyl tetrahydroisoquinolines that inhibit both dopamine and norepinephrine transporters were designed and prepared. In this Letter, we describe the synthesis, in vitro activity and associated structure-activity relationships of this series. We also report the ex vivo NET occupancy of a representative compound, 41.

O2 in, H2O out: Various diamines and related bisnucleophiles readily undergo oxidativeisocyanideinsertion with Pd(OAc)2 (1 mol %) as the catalyst and O2 as the terminal oxidant to give a diverse array of medicinally relevant N heterocycles. The utility of this highly sustainable method is demonstrated by a formal synthesis of the antihistamines astemizole and norastemizole.
O 2 in,H 2 O out:各种二胺和相关的双亲核试剂易于经历氧化异氰化物的插入,其中Pd(OAc)2(1 mol%)作为催化剂,O 2作为末端氧化剂,可得到多种与医学相关的N杂环。抗组胺药阿司咪唑和去甲阿司咪唑的正式合成证明了这种高度可持续性方法的实用性。

1,2,3,4-Tetrahyro-2-methyl-4-phenylisoquinolines 6 are obtained from aromatic aldehydes 1, methyl amine and α-haloacetophenones 2 in the presence of sodium borohydride followed by cyclization with sulfuric acid and zinc in methanol.

types of aliphaticsulfonylhalides (Cl versus F) were compared in parallel synthesis of sulfonamides derived fromaliphatic amines. Aliphaticsulfonyl fluorides showed good results with amines bearing an additional functionality, while the corresponding chlorides failed. Both sulfonylhalides were effective in the reactions with amines having an easily accessible amino group. Aliphaticsulfonyl chlorides

C1, seen them all: A catalytic transformation that uses CO2 as an oxygen‐free C1 building block is presented. The reductive functionalization of CO2 is promoted by N‐heterocyclic carbenes or guanidines as organocatalysts in the presence of amines and hydrosilanes. This diagonal strategy selectively affords benzimidazoles, quinazolinones, 3,4‐dihydroquinazolines, formamidines, and their derivatives
C 1,它们全都被看到:提出了使用CO 2作为无氧C 1构件的催化转化。在胺和氢硅烷存在下,N-杂环卡宾或胍作为有机催化剂促进了CO 2的还原功能化。这种对角策略可在温和条件下直接从CO 2直接选择性提供苯并咪唑,喹唑啉酮,3,4-二氢喹唑啉,甲am及其衍生物。

Maleimide‐mediated thiol‐specific derivatization of biomolecules is one of the most efficacious bioconjugation approaches currently available. Alarmingly, however, recent work demonstrates that the resulting thiomaleimide conjugates are susceptible to breakdown via thiol exchange reactions. Herein, we report a new class of maleimides, namely o‐CH2NHiPr phenyl maleimides, that undergo unprecedentedly
