A series of novel aralkyl piperazine derivatives were synthesized, and evaluated for their serotonin reuptake inhibitory and 5-HT1A/5-HT7 receptors affinities activity. Antidepressant activities in vivo of the compounds were screened using the forced swimming test (FST) and tail suspension test (TST). The results indicated that compounds 21k (RUI, IC50 = 31 nM; 5-HT1A, 5-HT7, ki = 62, 12 nM) and 21n (RUI, IC50 = 25 nM; 5-HT1A, 5-HT7, ki = 28, 3.3 nM) exhibited high affinities for the 5-HT1A/5-HT7 receptors coupled with potent serotonin reuptake inhibition. Specifically, the most promising compound 21n possessed a good oral pharmacokinetic properties and an acceptable hERG profile, and showed potent antidepressant-like effect in the FST and TST models.

Efficient Difluoromethylation of Alcohols Using TMSCF2Br as a Unique and Practical Difluorocarbene Reagent under Mild Conditions

A general method for the efficient difluoromethylation of alcohols using commercially available TMSCF2Br (TMS=trimethylsilyl) as a unique and practical difluorocarbene source is developed. This method allows primary, secondary, and even tertiary alkyl difluoromethyl ethers to be synthesized under weakly basic or acidic conditions. The reaction mainly proceeds through the direct interaction between a neutral alcohol and difluorocarbene, which is different from the difluoromethylation of phenols. Moreover, alcohols containing other moieties that are also reactive toward difluorocarbene can be transformed divergently by using TMSCF2Br. This research not only solves the synthetic problem of difluorocarbene-mediated difluoromethylation of alcohols, it also provides new insights into the different reaction mechanisms of alcohol difluoromethylation and phenol difluoromethylation with difluorocarbene species.

Constructing iboga alkaloids via C-H bond functionalization: Examination of the direct and catalytic union of heteroarenes and isoquinuclidine alkenes

, p. 2062 - 2071 (2015/10/12)
The iboga alkaloids have attracted considerable attention in both the scientific community and popular media due to their reported ability to reverse or markedly diminish cravings for, and self-administration of, the major drugs of abuse. We have developed three new intramolecular C-H functionalization procedures leading to the core seven-membered ring of the iboga skeleton, a cyclization that proved to be highly challenging. The electrophilic palladium salt Pd(CH3CN)4(BF4)2 was effective for the cyclization of diverse N-(2-arylethyl)isoquinuclidines with yields of 10-35%. A two-step, bromination-reductive Heck reaction protocol was also effective for the synthesis of ibogamine in 42% yield. Finally, a direct Ni(0)-catalyzed C-H functionalization provided the benzofuran analogues of ibogamine (74%) and epi-ibogamine (38%). Although each approach suffers from significant shortcomings, in combination, the methods described provide practical routes to diverse ibogamine analogues.
