合成路线:The reaction of cyclohexane-1,3-dione (I) with ammonia gives 3-amino-2-cyclohexen-1-one (II),which is cyclized with acrylic acid (III) by heating at 140 C yielding 1,2,3,4,5,6,7,8-octahydroquinoline-2,5-dione (IV).The dehydrogenation of (IV) by means of Pd/C in refluxing decaline affords 5-hydroxy-1,2,3,4-tetrahydroquinolin-2-one (V),which is condensed with epichlorohydrin (VI) by means of NaOMe or NaOH in methanol giving 5-(2,3-epoxypropoxy)-1,2,3,4-tetrahydroquinolin-2-one (VII).Finally,this compound is treated with tert-butylamine in methanol.
