Abstract

Recent catalytic methods to construct medium-sized lactams­ and partially saturated benzazepines and their derivatives are surveyed. The review is divided into the following sections:

1 Introduction

2 Non-Transition-Metal-Catalyzed Reactions

2.1 Beckmann Rearrangement

2.2 Non-Beckmann Rearrangement Reactions

2.3 Multicomponent reactions

3 Transition-Metal-Catalyzed Reactions

3.1 Gold-Catalyzed Reactions to Access Medium-Sized N-Hetero­cycles

3.2 Reactions Involving a Metal η3-Complex Catalytic Intermediate

3.3 Transition-Metal-Catalyzed Reactions of Strained Cycloalkanes

4 Conclusions
