Multicomponent Syntheses of Macrocycles

How to access efficiently the macrocyclic structure remained to be a challenging synthetic topic. Although many elegant approaches/reactions have been developed, construction of diverse collection of macrocycles is still elusive. This chapter summarized the recently emerged research area dealing with multicomponent synthesis of macrocycles, with particular emphasis on the approach named “multiple multicomponent reaction using two bifunctional building blocks”

War: Back to the Future

Annual Review of Anthropology, 1999.War is a fraught subject. Those who study it often fight about it. This chapter examines the current state of the study of war, described and analyzed by anthropologists and nonanthropologists who employ concepts like culture in writing about the future of war.
