由生物源和人为源排放的挥发性有机化合物（VOCs）与大气氧化剂发生复杂的反应，生成可形成二次有机气溶胶（SOA）的低挥发性有机物种。SOA占对流层细颗粒物质量的80%，可以显著影响空气质量，公众健康和气候。由陆地植被排放的生物源挥发性有机化合物（BVOCs），包括异戊二烯和萜烯，占全球VOC排放量的90%，并在很大程度上贡献了总SOA预算。然而，由于涉及复杂的化学过程，从BVOCs形成SOA仍处于活跃的研究中。为了准确地识别和量化SOA组件并阐明其形成机制，需要真实的标准，并且由于其商业不可用，通常需要合成。本文综述了在合成SOA指纹标记化合物方面取得的巨大进展。本文按照各化合物的氧化反应途径，系统地整理了最新的合成方法。这篇综述展示了有机合成在理解空气质量和气候变化方面的重要性，并为进一步将大气科学与有机化学联系起来提供了未来的方向。
Volatile organic compounds (VOCs) emitted by biogenic and anthropogenic sources undergo complex reactions with atmospheric oxidants to generate low-volatility organic species that can form secondary organic aerosols (SOA). SOA accounts for up to 80% mass of the tropospheric fine particulate matter and can significantly impact air quality, public health, and climate. Biogenic VOCs (BVOCs) emitted by terrestrial vegetation, including isoprene and terpenes, account for 90% of the global VOC emission and largely contribute to the total SOA budget. However, the formation of SOA from BVOCs is still under active research due to the complex chemistry involved. To accurately identify and quantify the SOA components and elucidate their formation mechanisms, authentic standards are necessary and often need to be synthesized due to their commercial unavailability. This review summarizes the tremendous progress made in synthesizing marker compounds that fingerprint SOA originating from key BVOCs. The up-to-date synthetic procedures in this article are systematically organized by the oxidation reaction pathways of each BVOC. This review demonstrates the importance of organic synthesis in understanding air quality and climate change, and provides future directions to further connect atmospheric sciences with organic chemistry.
