The tetrahydroisoquinoline alkaloids have been studied thoroughly about their biological and chemical significance over the past 30 years. These natural products show great biological activity, especially ET-743 and saframycin A, makes them promising therapeutics, while their structural complexity and particularity provide challenging synthetic targets. These alkaloids or derivatives show interesting biological activity, but the most important drawback as potential market therapeutics is the minute amount of them available from nature, and the synthetic methods published are inconvenient, difficult, and hard to handle. Herein is described our researches about the tetrahydroisoquinoline alkaloids. Chapter 1 describes relevant background related to the biological significance of these alkaloids, and the currently synthetic studies toward these natural products. Chapter 2 describes our design and synthesis of the analogues based on the anticancer mechanism of the tetrahydroisoquinoline alkaloids, and the biological activities of these analogues. Chapter 3 describes a rapid synthetic route for the common structure of the bis-tetrahydroisoquinoline alkaloids via a controlled mono-Pictet-Spengler cyclization.
