Description
Niniejszy wynalazek dotyczy sposobu wytwarzania kwasu L-piroglutaminowego lub jego pochodnych.The present invention relates to a process for the production of L-pyroglutamic acid or its derivatives.
Opis patentowy włoski nr 1 202 426 ujawnia kwas L-piroglutamylo-L-tiazolidyno-4-karboksylowy o właściwościach immunostymulujących, antytoksycznych, przeciwzapalnych, przeciwutleniających i przeciwstarzeniowych, który wytwarza się wychodząc z reaktywnego estru kwasu L-piroglutaminowego lub z jego chlorku kwasowego i kwasu L-tiazolidyno-4-karboksylowego.Italian Patent No. 1 202 426 discloses L-pyroglutamyl-L-thiazolidine-4-carboxylic acid with immunostimulating, antitoxic, anti-inflammatory, antioxidant and anti-aging properties, which is produced starting from the reactive ester of L-pyroglutamic acid or from its acid chloride and acid L-thiazolidine-4-carboxylic acid.
W szczególności, sposób wykorzystuje, np., reaktywne estry kwasu L-piroglutaminowego z pentachlorofenolem, pentafluorofenolem, 2,4,5-trichlorofenolem, N-hydroksysukcynimidem, hydroksyftalimidem, które poddaje się reakcji z kwasem L-tiazolidyno-4-karboksylowym w rozpuszczalnikach aprotycznych w obecności zasad trzeciorzędowych, lub chlorek kwasu L-piroglutaminowego, który poddaje się reakcji z kwasem L-tiazolidyno-4-karboksylowym w środowisku zasadowym.In particular, the method uses, e.g., reactive esters of L-pyroglutamic acid with pentachlorophenol, pentafluorophenol, 2,4,5-trichlorophenol, N-hydroxysuccinimide, hydroxyphthalimide, which are reacted with L-thiazolidine-4-carboxylic acid in aprotic solvents in the presence of tertiary bases, or L-pyroglutamic acid chloride which is reacted with L-thiazolidine-4-carboxylic acid in a basic medium.
Włoskie zgłoszenie patentowe nr 19401 A/89 opisuje pochodne kwasu 3-(L-piroglutamylo)-L-tiazolidyno-4-karboksylowego, o takich samych właściwościach farmakologicznych, wytwarzane podobnymi sposobami z reaktywnych estrów lub amidów kwasu L-piroglutamylo-L-tizaolidyno-4-karboksylowego i alkoholi lub amin.Italian patent application No. 19401 A / 89 describes 3- (L-pyroglutamyl) -L-thiazolidine-4-carboxylic acid derivatives with the same pharmacological properties, prepared by similar methods from reactive esters or amides of L-pyroglutamyl-L-tizaolidine-acid. 4-carboxylic acid and alcohols or amines.
Sposoby te mająpewne cechy niekorzystne z praktycznego punktu widzenia, mianowicie: kłopotliwe procesy z nadmiernie niskimi wydajnościami całkowitymi, użycie substancji wysoce toksycznych dla człowieka oraz środowiska, takich jak chlorowcofenole, stosowanie chlorku L-piroglutamylu, który bardzo trudno wytworzyć i którym trudno operować i niska trwałość reaktywnych estrów kwasu L-piroglutaminowego z N-hydrosukcynimidem i N-hydroksyftalimidem.These methods have some disadvantages from a practical point of view, namely: cumbersome processes with excessively low total yields, the use of substances highly toxic to humans and the environment, such as halophenols, the use of L-pyroglutamyl chloride, which is very difficult to produce and which is difficult to handle, and low durability reactive esters of L-pyroglutamic acid with N-hydrosuccinimide and N-hydroxyphthalimide.
Opis patentowy włoski nr 1239029 ujawnia sposób, w którym wyżej wspomniane problemy częściowo rozwiązano za pomocą prostszego procesu, bez użycia szczególnie toksycznych substancji, pracochłonnych i/lub nietrwałych półproduktów oraz z wyższymi wydajnościami. Taki proces unaocznił zaskakującą trwałość tiazolidyno-4-karboksylanu etylu, dając wydajności zasadniczo wyższe niż uzyskane w przypadku innych prostych estrów, takich jak metylowy i izopropylowy.Italian Patent No. 1,239,029 discloses a method in which the above-mentioned problems are partially solved by a simpler process, without the use of particularly toxic substances, labor-intensive and / or unstable intermediates, and with higher yields. This process demonstrated the surprising stability of the ethyl thiazolidine-4-carboxylate with yields substantially higher than those obtained with other simple esters such as methyl and isopropyl.
Obecnie stwierdzono, że wspomniany sposób można dalej ulepszyć, uzyskując niemal ilościowe wydajności żądanych produktów, kondensując tiazolidyno-4-karboksylan etylu lub jego pochodną z pochodną kwasu L-piroglutaminowego w apolamych rozpuszczalnikach aprotycznych i hydrolizując ostatecznie ester etylowy w warunkach przeniesienia międzyfazowego.It has now been found that said process can be further improved to near quantitative yields of the desired products by condensing ethyl thiazolidine-4-carboxylate or a derivative thereof with a L-pyroglutamic acid derivative in aprotic solvents and finally hydrolyzing the ethyl ester under phase transfer conditions.
