## Abstract A reβexamination of the reaction of Ξ±βangelica lactone with methylamine in water confirmed that 5βhydroxyβ1,5βdimethylpyrrolidinβ2βone (5) was formed almost quantitatively in a very fast reaction. Dehydration of this compound by vacuum distillation, however, unexpectedly afforded 1βmeth
