The use of 2, 6-dimethylmorpholine as an amine moiety in Mannich reaction has been investigated. Nine new Mannich bases have been synthesized using nine different ketones. The salts of β -amino esters have also been synthesized by Mannich reaction using p -nitrophenylacetic acid, formaldehyde solution (37 per cent), and three different amines (2, 6-dimethylmorpholine, piperidine, and 4-methylpiperidine)

rhodium(II)-acetate-catalyzed decomposition of 3-(4-acetoxyphenyl)-1-diazo-4-(pyrrol-1-yl)-2-butanone (5d) gave 6-(4-acetoxyphenyl)-5,6-dihydro-7(8H)-indolizinone (6d) in 82% yield via an intramolecular carbenoidreaction. The latter compound was converted in four steps in 13% overall yield to (±)-ipalbidine (1b).
