制备方法与用途

化学性质

(1-溴萘-4-基)甲醇为白色结晶或结晶粉末，在有机溶剂如醇和醚中具有良好溶解性，但在水中不溶。

用途

在工业应用中，(1-溴萘-4-基)甲醇主要用于合成染料、香料和杀虫剂等产品。

合成方法

室温下，将乙酸（4-溴-1-萘基）甲酯（14.97克，53.63毫摩尔）与氢氧化钠（3.22克，80.4毫摩尔）在甲醇（50毫升）、水（30毫升）和四氢呋喃（30毫升）的混合液中搅拌30分钟。浓缩反应溶液后用水稀释，并用乙酸乙酯萃取两次。收集有机层，使用无水硫酸钠干燥并减压蒸发溶剂。通过硅胶柱色谱纯化（己烷/乙酸乙酯=3/1-2/1），再从乙酸乙酯-己烷中结晶得到目标物质。最终获得白色晶体11.77克，收率93%。

  Direct C-H functionalization of aromatic compounds is a powerful tool for organic synthesis; however, differentiation amongst the ubiquitous and often chemically similar C-H bonds remains a significant challenge. Conflation with coordinating or directing groups incorporated into the intended substrate has helped address these limitations, although access to remote sites remains limited. Herein, we

  The present invention provides small-molecule inhibitors of BMP signaling and compositions and methods for inhibiting BMP signaling. These compounds and compositions may be used to modulate cell growth, differentiation, proliferation, and apoptosis, and thus may be useful for treating diseases or conditions associated with BMP signaling, including inflammation, cardiovascular disease, hematological disease, cancer, and bone disorders, as well as for modulating cellular differentiation and/or proliferation. These compounds and compositions may also be used to reduce circulating levels of ApoB-100 or LDL and treat or prevent acquired or congenital hypercholesterolemia or hyperlipoproteinemia; diseases, disorders, or syndromes associated with defects in lipid absorption or metabolism; or diseases, disorders, or syndromes caused by hyperlipidemia.

  Asymmetric benzylation of prochiral azlactone nucleophiles enables the catalytic introduction of a benzyl group towards the synthesis of α,α‐disubstituted amino acids. Herein, we report an enantioselective palladium‐catalyzed process using chiral bis(diphenylphosphinobenzoyl)diamine (dppba) ligands. Naphthalene‐ and heterocycle‐based methyl carbonates react with a number of azlactones derived from

  esters is reported. This reaction proceeds via stereodefined C1‐ammonium enolate nucleophiles. Critical to its success was the identification of benzylic phosphate electrophiles, which were uniquely reactive. Alkylated products were obtained with very high levels of enantioselectivity, and this method has been applied toward the synthesis of the thrombin inhibitor DX‐9065a.
