- W2023214510 abstract "α-Amino-hexin-(5)-carbonsauren (II) lassen sich nicht durch alkalische bzw. saure Hydrolyse aus 5-Butinyl-hydantoinen (I) darstellen. Nach kurzerer Einwirkungszeit (2 1/2 bis 5 Std.) von 15proz. HCl erfolgt Wasseranlagerung an die Dreifachbindung, es entstehen Oxoalkyl-hydantoine (IV). Mit starkerer Salzsaure (25%) und langerer Einwirkung entstehen Pyrrolin-carbonsauren (III). Letztere treten auch dann auf, wenn die Butinyl-hydantoine mit Barytlauge bei 150° (15 atu) verseift werden. Propinyl-cycloalkanspirohydantoine (VII) verhalten sich bei saurer Hydrolyse gleich; es bilden sich Cycloalkanopyrrolin-carbonsauren (IX).Δ1-Pyrrolines from Alkinyl-hydantoinsα-Amino-5-hexyne carboxylic acids (II) cannot be synthesized from 5-butynyl-hydantoins by alkaline or acidic hydrolysis. After a shorter reaction time (2 1/2 to 5 hours) with approximately 15% hydrochloric acid, addition of water to the triple bond takes place resulting in oxoalkyl-hydantoins (IV). Pyrroline carboxylic acids (III) are formed under the action of stronger hydrochloric acid (about 25%) during a longer reaction time. These reaction products are also obtained if the butynyl-hydantoins are saponified by barium hydroxide at 150° C (220 p. s. i.). Propynyl-cycloalkyl-spiro-hydantoins (VII) show the same behaviour towards acidic hydrolysis; cycloalkyl-pyrroline carboxylic acids (IX) are formed." @default.
