Title:
METHOD FOR RELEASING COMPOUND
Document Type and Number:
WIPO Patent Application WO/2021/177343
Kind Code:
A1
Abstract:
Provided is a method in which a caged compound represented by general formula (I) is irradiated with light in the presence of a photosensitizer to thereby release a compound represented by general formula (II). In cases when X is O, the compound represented by general formula (II) is a compound represented by general formula (IIA). In cases when X is NH, the compound represented by general formula (II) is a compound represented by general formula (IIB). In cases when X is a bond, the compound represented by general formula (II) is a compound represented by general formula (IIC).
