| abstract | NEW MATERIAL:A compound shown by the formula I (R is 1W5C alkyl). n EXAMPLE: 5(S)-t-Butyldimethylsilyloxymethyl-2-pyrrolidone. n USE: An intermediate for synthesizing domoic acid as an insecticide. n PREPARATION: L-Pyrrolidonecarboxylic acid is subjected to methyl esterification to give 5-oxo-2(S)-pyrrolidinecarboxylic acid methyl ester compound shown by the formula II. Then, this compound is reduced with a metallic hydride (e.g., sodium boron hydride, etc.), to give 5(S)-hydroxymethyl-2-pyrrolidone compound shown by the formula III. This compound is treated with a trialkylchlorosilane (e.g., t-butyldimethylchlorosilane, etc.) in a solvent such as preferably methylene chloride, etc., in the presence of an excess amount of a tertiary amine such as triethylamine, etc., and a catalytic amount of 4- dimethylaminopyridine. n COPYRIGHT: (C)1986,JPO&Japio |
