L-Proline

Product Description:
White crystals / 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 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.
