Stereochemistry of bicyclic compounds
網頁In this article, we report the total synthesis of 6-deoxydihydrokalafungin (DDHK), a key biosynthetic intermediate of a dimeric benzoisochromanequinone antibiotic, actinorhodin (ACT), and its epimer, epi-DDHK. Tricyclic hemiacetal with 3-siloxyethyl group was subjected to Et3SiH reduction to establish the 1,3-cis stereochemistry in the … 網頁Chapter 7 – Cyclic Compounds. Stereochemistry of Reactions Introduction Chapter 7 deals with two topics using tools and concepts developed in earlier chapters. As such, it provides a nice “rest stop” before diving into the new chemical reactions in chapter 8.
