Kokai Tokkyo Koho JP 03255046 A2 13 Nov 1991 Heisei, 7 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C07C049-707. ICS: B01J031-02; C07C045-64. ICA: C07B053-00; C07B061-00; C07D303-32. APPLICATION: JP 90-47244 1 Mar 1990. DOCUMENT TYPE: Patent CA Section: 24 (Alicyclic Compounds) 4-Hydroxy-2-cyclopentenones with high optical activity are prepd. by asym. isomerization of 3,4-epoxycyclopentanone (I) in the presence of Al trialkoxides and optically active 2,2'-dihydroxy-1,1'-binaphthyl (1,1'-bi-2-naphthol) (II). Thus, 98.7 mg I was stirred in 1:200 EtOH-CHCl3 mixt. in the presence of (Me2CHO)3Al, (R)-(+)-II, and p-O2NC6H4OH at 19° for 49 h to give 93% (R)-4-hydroxy-2-cyclopentenone in 91% e.In this experiment, several chemicals are used like 18531-94-7 and 59995-47-0 e. .
