We have synthesized and evaluated a series of diketopiperazine-based inhibitors of PAI-1. These studies resulted in the identification of 34 which inhibited PAI-1 in vitro with an IC50 = 0.2 μM. The synthesis and SAR of these compounds are desc
Potassium Fluoride on Alumina: Condensation of 1,4-Diacetylpiperazine-2,5-dione with Aldehydes. Dry Condensation under Microwave Irradiation. Synthesis of Albonursin and Analogues

1,4-Diacetylpiperazine-2,5-dione (1) was condensated with aldehydes (2) with KF on alumina without solvent under microwaves or in at room temperature in the presence of DMF.The reaction was stereoselective and some natural products (4a-c) like albonursin (4c) were synthesized.

The preparation of mono- and of symmetrical and unsymmetrical bis-ylidene derivatives of piperazine-2,5-dione is described.The uv-visible absorption of the products is correlated with acceptor/donor character of the substituents.

It was shown that N-(4-methoxybenzyl) group on 2,5-piperazinediones can be oxidatively removed with cerium(IV) diammonium nitrate under mild conditions, and the oxidative removal was performed in some model compounds which have several functional groups.
