The invention also relates to novel substituted lactams, libraries comprising such lactams, and a method of generating libraries substituted lactams, using the method of the invention.
The invention concerns a method for purifying lactams, more particularly lactams obtained by cyclizing hydrolysis of aminonitrile.
The invention concerns a method for treating lactams.
Some β-lactams are less sensitive to β-lactamase.
The present invention is directed to a process for the preparation of β-lactams.
In such a process essentially no β-lactam core and β-lactam antibiotic are lost.
A method of separating enantiomeric lactam esters.
The invention relates to a lactam production method.
The present invention relates to the degradation of β-lactam compounds such as penicillins in the presence of other β-lactam compounds such as cephalosporins.
The present invention relates to improved processes for preparing lactam morphinans.
The hydrolysis product is then separated from the unreacted lactam esters.
The present invention further relates to novel N-substituted γ-methylene γ-lactams.
It can contain prepared mixtures of the beta-lactams and chromogenic substrate.
Growth promoting compositions containing such benzo-fused lactams as the active ingredient thereof are also disclosed.
The invention is directed to an improved process for the preparation of spirocyclic lactams which utilizes diiodides in the spiro alkylation of lactams N-substituted with a tertiary amine group.
The invention relates to copolymers of vinyl lactams with derivatized maleates.
The present invention relates to a method for preparing lactams by cyclising hydrolysis of a corresponding aminonitrile.
Unfortunately, these inhibitors are also ß-lactams, and resistance to them has developed rapidly.
Growth promoting compositions containing such benzo-fused lactams as the active ingredient thereof are also disclosed.
More specifically, the invention relates to processes of producing β-lactam antibiotics in vivo and in vitro.
