Title:
5-BENZYLOXY-1,2,3,4-TETRAHYDRONAPHTHALENE DERIVATIVE AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2005120027
Kind Code:
A
Abstract:
To solve the problems wherein a well-known method for producing an important intermediate is insufficient for a large-scale industrial production in a cost field and an environmental field because an expensive trimethylsilyl cyanide is used in the process, and further a compound of tin which is a heavy metal is used.
The production method for obtaining optically pure 5-benzyloxy-1,2,3,4-tetrahydronaphthalene-1-carboxylic acid through 5-benzyloxy-1,2,3,4-tetrahydronaphthalene-1-carbonitrile involves using an inexpensive reaction reagent easily made harmless.
