Compounds are provided that modulate the glucagon-like peptide 1 (GLP-1) receptor, as well as methods of their synthesis, and methods of their therapeutic and/or prophylactic use. Such compounds can act as modulators or potentiators of GLP-1 receptor on their own, or with incretin peptides such as GLP-1(7-36) and GLP-1(9-36), or with peptide-based therapies, such as exenatide and liraglutide, and have the following general structure (where "^^^^" represents either or both the R and S form of the compound) (I) where A, B, C, Y1, Y2, Z, R1, R2, R3, R4, R5, W1, n, p and q are as defined herein.
Chemists devote tremendous effort to the precise placement of oxygens in molecular frameworks. Wu
et al
. report a convenient method to shift the oxygen in a carbonyl group to an adjacent carbon center. After activation of the oxygen to an alkenyl triflate, cooperative catalysis by palladium and norbornene adds nitrogen to the neighboring carbon while displacing the triflate with hydride. Hydrolysis then produces the desired shifted ketone. The protocol is well suited to late-stage variation of complex molecules during drug optimization. —JSY

4-substituted cyclohexanones (R = Me, Et, n-Pr, i-Pr, allyl, n-Bu), almost all of which were oxidized to the corresponding e-caprolactones in good yields and high enantioselectivities (typically ≥ 95%). Mesomeric 4-substituted cyclohexanones were oxidized to e-caprolactones in ≥ 92% ee. The engineered yeast strain also effected kinetic resolutions of 2-substituted cyclohexanones with enantioselectivity values

nondirected, electrophilic metal–catalyzed aminations tend to bind to and thereby inhibit metal catalysts. We reasoned that an autoregulatory mechanism coupling the release of amine nucleophiles with catalyst turnover could enable functionalization without inhibiting metal-mediated heterolytic carbon-hydrogen cleavage. Here, we report a palladium(II)-catalyzed allylic carbon-hydrogen amination cross-coupling
末端烯烃与仲胺的分子间交叉偶联形成复杂的叔胺(药物中的常见基序)仍然是化学合成的主要挑战。非定向亲电金属催化胺化中的碱性胺亲核试剂倾向于结合并抑制金属催化剂。我们推断,将胺亲核试剂的释放与催化剂周转相结合的自动调节机制可以在不抑制金属介导的异裂碳氢裂解的情况下实现功能化。在这里,我们使用这种策略报告了钯 (II) 催化的烯丙基碳-氢胺化交叉偶联,具有 48 个环状和无环仲胺(10 个药学相关核)和 34 个末端烯烃(带有亲电官能团),以提供 81 个叔烯丙基胺类,乙:Z)。

Compounds and methods for use in detecting gabapentin in a sample suspected of containing gabapentin are disclosed. Gabapentin derivatives are used to produce gabapentin conjugates. A gabapentin-immunogenic carrier conjugate may be used as an immunogen for the preparation of an anti-gabapentin antibody. A gabapentin-detectable label may be used in a signal producing system in gabapentin assays.
