PROCESS FOR THE PREPARATION OF 5-ARYLIDENE HYDANTOINS |
| abstract |
10 TO 100 MOLES OF AN ARYLIDENE-IMINE AND 90 TO 0 MOLES OF AROMATIC ALDEHYDE OF WHICH AROMATIC ARYLIDENE DERIVED FROM WHICH ARYLIDENE-IMINE DERIVED WITH NON-SUBSTITUTED OR SUBSTITUTED HYDANTOIN IN 1, 3 OR 3 OR POSITIONS 1, DERIVED 1 AND 3. ARLIDENE-IMINE IS USED IN THE PURE STATE OR FORMED IN SITU FROM AROMATIC ALDEHYDE AND IN A 0.1 TO 1.0 MOLAR QUANTITY OF AMMONIA OR A PRIMARY AMINE. THE PROCESS ACCORDING TO THE INVENTION GIVES THE SOUGHT-AFTER PRODUCTS, WHICH ARE IMPORTANT INTERMEDIATE PRODUCTS IN THE PREPARATION OF PHENYLALANINES, WITH ALMOST QUANTITATIVE YIELDS. |
