Document Type and Number:
Japanese Patent JP2969542
Kind Code:
B2
Abstract:
PURPOSE: To provide a novel compound excellent in water resistance and hydrolysis resistance and useful as a physio1ogically active substance, afunctional substance or an intermediate for the substances.
CONSTITUTION: A compound of formula I (R1, R2, R3 are-COOH,-COOCH3,- COOC2H5,-CH2OH,-COCH3, H, 1-5C alkyl, etc.; R4 is H,-OH, 1-5C alkyl, etc.,), e.g. The compound of formula I is obtained by subjecting a compound of formula II to a Koch-Haaf reaction for introducing the carboxyl group and subsequently esterifying the produced carboxylic acid. The compound of formula I is a compound in which the various substituent have been introduced to the tetracyclo[7.3.1.02,7.17,11] tetradecane skeleton that is more bulky than adamantane and extremely excellent in hydrophobicity. The skeleton has high selectivity that the substituents have been introduced to the 1,9,11 positions but not introduced to the other positions in all cases except a case in which a hyclroxyl group has been introduced to the 2 position.
