Mono- and Bicyclic Systems

摘要: The concept of shift additivity that was developed in Chapter 1 with acyclic systems can be extended to cover cyclic arrays as well. Unfortunately, each ring system has unique features and a relatively simple but “universal” set Δδ values such found Table 1–1 will too general provide accurate predictions for mono- especially polycyclic systems. It is this reason we have gathered the extensive sets carbon data following chapters individually virtually all bicyclic are commonly used synthesis. Thus, while substituents differ from one another even between positions on given framework, majority these book. In addition, applied directly tri- tetracyclic by an analysis treats local area part subunit.
