    摘要: The invention relates to a novel process for the preparation of 1-[3-mercapto-(2S)-methylpropionyl]-pyrrolidine-(2S)-carboxylic acid through the N-acylation of L-proline.According to the process of the invention L-proline is acylated with a 3-halogen-2-methylpropionyl chloride of the formula III ##STR1## wherein Hal is a halogen atom, preferably chlorine or bromine, the obtained 1-[3-halogen-(2S)-methylpropionyl]-pyrrolidine-(2S)-carboxylic acid, wherein Hal is as stated above, is reacted with an alkali thiosulfate or alkali trithiocarbonate and the reaction product is hydrolized with an acid.The process of the invention is very economical as compared with the known processes. The desired product is prepared from methacrylic acid in 4 reaction steps with a total yield of 25 percent and from L-proline in 2 reaction steps with a total yield of 30 percent.

    摘要: Keys which are used in a keyboard of a miniaturized data processing device include an upper surface which is provided with a downwardly-extending wall running transversely to the movement of the finger when operating the keys. The downwardly-extending wall, which is formed, for example, by a groove disposed in the upper surface, serves as a support for the tip of a user's fingernail when operating the keys. Such keys make possible an accurate operation even if the keys are disposed closely side by side in a miniaturized key board and the fingernail is fashionably long.
