Ionic liquids (IL)s represent an attractive and potentially very valuable group of new solvents, which have the benefit of low vapour pressure and therefore easier handling than many conventional solvents. These liquids, because of their unique properties, are attracting a lot of attention to replace volatile organic solvents, eco-friendly and green media.

Phthalic anhydride was reacted with L-phenylalanine in&nbsp

In modern synthetic organic chemistry laboratories protocols for convenient andrapid transformations are highly desired. Microwave activation has received considerable attention in recent years and it is a subject of intense debate in the scientific community. This technique as an alternative to conventional energy sources for introduction of energy into reactions has become a very well-known and practical method in various fields of chemistry.

The present paper is an extension of microwave method describing the synthesis of optically act
