The invention relates to compounds represented by the general formula (I): and pharmaceutically acceptable salts thereof, wherein n is an integer from 1 to 5; p is an integer from 0 to 4; R1 is selected from the group consisting of a hydroxyl group, an alkoxy group, a thiol group, and a thioether group; R2 and R3 are independently a methylene group or a nucleophile, with the proviso that at least one of R2 and R3 is a nucleophile group; Z is an oxygen (O) atom or sulfur (S) atom; T is hydrogen or an optionally substituted aliphatic group; with the proviso that when n = 2, R1 is not -OCH3 on the carbon-3 position of the phenyl group and R1 is not -OH on the carbon-4 position of the phenyl group.
The present invention relates to the use of a compound represented by the general formula (I), and pharmaceutically acceptable salts thereof, wherein: n is an integer from 2 to 5; p is an integer from 0 to 4; R1 is selected from the group consisting of a hydroxyl group, an alkoxy group, a thiol group, a thioether group, and an amino group, wherein at least two of R
1
is a hydroxyl group, a thiol group or an amino group, with the proviso that wherein n is 2, R
1
is not on the carbon-2 position and the carbon-5 position of the phenyl group; R
2
and R
3
are independently a methylene group or a nucleophile, with the proviso that at least one of R
2
and R
3
is a nucleophile group; Z is an oxygen (O) atom or sulfur (S) atom; T is hydrogen or an optionally substituted aliphatic group; in the manufacture of a medicament for treating a patient in need of cell therapy.

A fast and acid-free one-pot 0.2-30 mmol microwave methodology for direct ionic liquid-mediated preparation of lactams from lactones and primary amines has been developed. The protocol was investigated with a wide range of primary amines and a handful of lactones, including substrates with acid-sensitive substituents. Both gamma-lactams and delta-lactams were, despite the complete absence of a Bronsted acid. obtained in useful to excellent yields after only 35 min of microwave processing.
