METHOD FOR SYNTHESIZING MACROCYCLIC LACTONE BY PHOTODECARBOXYLATION REACTION

摘要

PROBLEM TO BE SOLVED: To provide a method for easily and inexpensively synthesizing a macrocyclic lactone by which the length of the carbon chain can be regulated freely.;SOLUTION: The method for synthesizing the macrocyclic lactone which is represented by formula (II) (wherein, n is an integer of 1-20) and which may be substituted includes a step for subjecting a carboxylic acid which is represented by formula (I) (wherein, n is the same as above) and which may be substituted, to photodecarboxylation reaction in the presence of a polycyclic carbon ring derivative and a cyanobenzene derivative.;COPYRIGHT: (C)2011,JPO&INPIT
