methodology was a key tool used to produce a synthesis intermediate with high optical purity. In addition, developing a tandem Mannich–aza-Michael reaction to obviate the need for a Curtis/acylation sequence and a novel reductive amination/thermal lactamization to circumvent Freidinger-type pyrrolidone preparation are some of the synthesisimprovements that enabled access to the target molecule to
