The enantioselective synthesis of such compounds, until the beginning of the 21st century, has been mostly achieved using transition-metal chiral catalysts. The explosion of enantioselective organocatalysis, however, has enabled the development of efficient metal-free methodologies with significant benefits in terms of costs and environmental safety. An overview of the advances made in recent years in this field is herein presented.<\/jats:p>","DOI":"10.3390\/sym16020199","type":"journal-article","created":{"date-parts":[[2024,2,8]],"date-time":"2024-02-08T03:36:17Z","timestamp":1707363377000},"page":"199","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Organocatalytic Conjugate Hydroazidation and Hydrocyanation: A Metal-Free Approach to Synthetically Versatile Chiral Building Blocks"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0515-424X","authenticated-orcid":false,"given":"Rosaria","family":"Schettini","sequence":"first","affiliation":[{"name":"Department of Chemistry and Biology \u201cA.
