Syntheses of Bioactive Natural Products and Natural-Product-Like Compounds Based on Their Key Structural Units

This account describes our recent efforts toward the syntheses of natural products and natural-product-like compounds. Developing new strategies based on the key structural unit present in a target molecule is our main focus in the journey leading to the total synthesis of natural products. 1 Introduction 2 Synthesis of Podophyllotoxin 3 Synthesis of Mesembrine 4 Synthesis of Hexahydropyrroloindole Alkaloids 5 Total Synthesis of Stenine 6 Synthesis of Brazilide A, Brazilin, and Aza-Brazilins 7 Synthesis of Important Structural Units Present in Natural Products and Pharmaceuticals 8 Summary
