20100305353 | METHOD FOR PRODUCING PURIFIED FORMYLCYCLOPROPANE COMPOUND AND INTERMEDIATE OF SUCH FORMYLCYCLOPROPANE COMPOUND - A method for producing a purified formylcyclopropane compound represented by the formula (1) comprising (A) a step of reacting a crude formylcyclopropane compound represented by the formula (1): | 12-02-2010 |
20110245529 | METHOD FOR PRODUCING OPTICALLY ACTIVE VINYLCYCLOPROPANECARBOXYLIC ACID DERIVATIVE AND OPTICALLY ACTIVE VINYLCYCLOPROPANEAMINO ACID DERIVATIVE - The objective of the present invention is to provide a method for obtaining an optically active vinylcyclopropanecarboxylic acid derivative with high yield and high optical purity using a safe material available at low cost. In addition, the objective of the present invention is to provide a method for safely-obtaining an optically active vinylcyclopropaneamino acid with high optical purity at low cost. The problems can be solved by a method for obtaining an optically active vinylcyclopropanecarboxylic acid derivative, which method contains the step of reacting a racemic vinylcyclopropanecarboxylic acid derivative with an optically active amine compound, to obtain a diastereomer salt of optically active vinylcyclopropanecarboxylic acid derivative-amine compound. In addition, it is possible to obtain a vinylcyclopropaneamino acid by deriving the vinylcyclopropaneamino acid from thus obtained diastereomer salt of optically active vinylcyclopropanecarboxylic acid derivative-amine compound. | 10-06-2011 |
