Reflecting the latest advances in protective group methodology, this Third Edition of the proven laboratory reference is expanded by more than 50%, providing readers with a comprehensive compendium of 1,050 of the most useful protective groups as well as 5,350 references to original publications. Protective groups are organized by six major organic functional groups: hydroxyl, amino, carboxyl, carbonyl, sulfhydryl, and phosphate groups (the last new to this edition). Also added in this edition are protection of the alkyne-CH, expanded coverage of protection of all groups, and many new enzymatic methods of protection and deprotection. Each chapter briefly describes the classes of available protective groups, followed by an in-depth look at the chemistry of individual protective groups, their properties, and the best methods of formation and cleavage. Ten reactivity charts with more than 28,000 entries summarize the relative reactivities of 270 commonly used protective groups with 108 reagents. This book will be an indispensable reference for synthetic chemists and students

For 40 years following the end of World War II, the Western democratic governments and the Eastern Bloc Communist powers were locked in the ideological, political, and economic struggle of the Cold War. The United States and the Soviet Union developed missile systems capable of delivering conventional and nuclear explosives against enemy massed bomber formations in the air, and of delivering retaliatory nuclear payloads against ground targets located on distant continents. The missile systems played both a defensive role, and a potential offensive role, which was parlayed to the public as deterrence against attack by the rival bloc. This title provides a detailed overview of the fixed-launch-site strategic missile systems of the United States.
