crystals or crystalline powder; slightly sweet taste. Very soluble
in water, freely soluble in glacial acetic acid, sparingly soluble
in ethanol, practically insoluble in ether.
L-Proline
Applications
L-Proline has
been found as an effective catalyst for the one pot synthesis of
polyhydroquinoline derivatives via four component Hantzsch
reaction. This method provides several advantages such as being
environmentally benign, possessing high yields with increased
variations of the substituents in the product and preparative
simplicity.
