  • Controlling Reactivity and Selectivity in the Mizoroki–Heck Reaction: High Throughput Evaluation of 1,5-Diaza-3,7-diphosphacyclooctane Ligands

    We report a high throughput evaluation of the Mizoroki–Heck reaction of diverse olefin coupling partners. Comparison of different ligands revealed the 1,5-diaza-3,7-diphosphacyclooctane (P2N2) scaffold to be more broadly applicable than common “gold standard” ligands, demonstrating that this family of readily accessible diphosphines has unrecognized potential in organic synthesis. In particular, two
    我们报告了对不同烯烃偶联伙伴的 Mizoroki-Heck 反应的高通量评估。不同配体的比较表明,1,5-二氮杂-3,7-二磷环辛烷 (P 2 N 2 ) 支架比常见的“金标准”配体具有更广泛的适用性,表明这一易于获得的二膦家族在有机领域具有未被认识到的潜力。合成。特别是,鉴定出两个结构相关的P 2 N 2配体能够实现苯乙烯的区域发散芳基化。通过简单地将磷取代基从苯基改为叔丁基,可以以高区域异构比获得直链和支链 Mizoroki-Heck 产物。进行了实验和计算机制研究以进一步探讨选择性的起源,这表明两种配体以类似的方式与金属配位,但磷取代基的刚性定位迫使与引入的烯烃以 π-π 相互作用接触(对于P-Ph 配体)或空间冲突(对于 P -t Bu 配体),决定了区域控制。
  • <i>N</i>-Alkoxyheterocycles As Irreversible Photooxidants

    AbstractIrreversible photooxidation based on N–O bond fragmentation is demonstrated for N‐methoxyheterocycles in both the singlet and triplet excited state manifolds. The energetic requirements for bond fragmentation are studied in detail. Bond fragmentation in the excited singlet manifold is possible for ππ* singlet states with energies significantly larger than the N–O bond dissociation energy of ca 55 kcal mol−1. For the * triplet states, N–O bond fragmentation does not occur in the excited state for orbital overlap and energetic reasons. Irreversible photooxidation occurs in the singlet states by bond fragmentation followed by electron transfer. Irreversible photooxidation occurs in the triplet states via bimolecular electron transfer to the donor followed by bond fragmentation. Using these two sensitization schemes, donors can be irreversibly oxidized with oxidation potentials ranging from ca 1.6–2.2 V vs SCE. The corresponding N‐ethylheterocycles are characterized as conventional reversible photooxidants in their triplet states. The utility of these sensitizers is demonstrated by irreversibly generating the guanosine radical cation in buffered aqueous solution.

    Herein, we report that highly chemoselective and enantioselective reduction of 2‐vinyl‐substituted pyridines has been achieved for the first time. The reaction, which uses chiral spiro‐bicyclic bisboranes as catalysts and HBpin and an acidic amide as reducing reagents, proceeds through a cascade process involving 1,4‐hydroboration followed by transfer hydrogenation of a dihydropyridine intermediate
