Vince lactam is the commercial name given to the bicyclic molecule γ-lactam 2-azabicyclo[2.2.1]hept-5-en-3-one. This lactam is a versatile chemical intermediate used in organic and medicinal chemistry. It is used as a synthetic precursor for three drugs (approved or in clinical trials). It is named after Robert Vince who has used the structural features of this molecule for the preparation of carbocyclic nucleosides. Vince's work with this lactam eventually led to his synthesis of abacavir. Peramivir synthesis is also dependent on Vince lactam starting material.
The Ojima lactam is an organic compound of some importance in the commercial production of Taxol. This lactam was first synthesized by Iwao Ojima. The organic synthesis is an illustration of asymmetric synthesis via a chiral auxiliary.
Neisseria lactamica is a gram-negative diplococcus bacterium. It is strictly a commensal species of the nasopharynx. Uniquely among the Neisseria they are able to produce β-D-galactosidase and ferment lactose.
