Shibata, T.Science of Synthesis: Stereoselective Synthesis, (20113125.

General Introduction

Various types of stereoselective [m+n+1] carbocyclizations have been reported. This chapter focuses on the carbonylative [2+2+1] reactions of enynes, namely the PausonKhand reaction, which yields synthetically important bicyclopentenones and has been comprehensively studied.[‌1‌] Other types of [m+n+1] carbocyclizations, including [3+2+1], [4+2+1], [5+2+1], and [4+4+1] reactions, are also mentioned, where the C1 source is carbon monoxide or (trimethylsilyl)diazomethane.
