Description
アミノ]ベンゾフェノンは90%以上回収が可能であり、ラセミ化が発生せず、次の反応に継続的に使用が可能であるので、経済的に非常に有利である。

ンゾフェノン、M(すなわち、Cu2+、Ni2+、またはZn2+)を含む塩またはその水和物、及びグリシンを反応させる段階と、を含む方法で製造されうる。前記化学式3の化合物の製造方法を反応式で要約すれば、反応式1の通りである。
オニル(SOCl2)存在下でジクロロメタンなどの通常の有機溶媒を使用して行える。すなわち、D−N−ベンジルプロリンのジジクロロメタン溶液を約−20〜−30℃に維持しつつ塩化チオニル(SOCl2)をゆっくり滴加した後、2−アミノベンゾフェノンを徐々に加えることによって反応を行える。
M(すなわち、Cu2+、Ni2+、またはZn2+)を含む塩またはその水和物、及びグリシンを反応させる段階は、水酸化カリウムなどの塩基存在下でメタノールなどのアルコールを溶媒として使用して約40〜50℃で行える。前記Cu2+、Ni2+、またはZn2+を含む塩としては、硝酸塩形態(例えば、Ni(NO3)2など)、ハロゲン塩形態(例えば、NiCl2、NiBr2など)、アセテート形態(例えば、Ni(OAc)2など)、または硫酸塩形態(例えば、NiSO4など)でありうる。また、前記Cu2+、Ni2+、またはZn2+を含む塩の水和物としては多様な形態の水和物を使用でき、望ましくはNi(NO3)2・6H2Oを使用できる。
D−プロリン(115g,1mol)、水酸化カリウム(168.3g,3mol)、及びイソプロピルアルコール(1L)の懸濁液を40℃で攪拌した。懸濁液が透明になった後、ベンジルクロライド(137.3g,1.1mol)を徐々に添加して40℃で6時間攪拌した。反応液を0〜5℃に冷却した後、濃塩酸(145mL)でpHを5〜6に調節した。この反応液をクロロホルム(3L)で希釈して18時間攪拌した後、生成された塩化カリウムを濾過して除去した。濾液を濃縮してアセトンで再結晶して表記化合物161.8g(収率79%)を製造した。
