The asymmetric synthesis of (-) - and (+) -cucurbitine was carried out by a method involving 1, 3-dipolar cycloaddition of the intermediary azomethine ylide and pig liver esterase (PLE) - catalyzed hydrolysis. The thio analogue, (-) -3-aminotetrahydrothiophene-3-carboxylic acid, was also synthesized.
通过中间偶氮甲碱叶立德的1, 3-偶极环加成和猪肝酯酶(PLE)催化水解的方法进行了(-)-和(+)-葫芦碱的不对称合成。还合成了硫代类似物(-)-3-氨基四氢噻吩-3-羧酸。
