Cycloadditions in Syntheses. Part 28. 2-Azabicyclohexane-3,5-dione and its Derivatives: Synthesis and Transformation to Azetidin-2-ones

2-Azabicyclohexane-3,5-dione has been synthesized via photopyridone formation from 4-(dimethyl-t-butylsiloxy)- or 4-alkoxy-2-pyridones followed by mild acid hydrolysis.The title compound and its derivatives react with a variety of nucleophiles (ROH

A novel synthesis of the carbapen-2-em ring system

A new synthesis of the carbapenem ring system, as found in thienamycin and related natural products, has been developed. The key step involves a highly efficient carbene insertion reaction which produces the bicyclic ring system by forming the N3 bond.
