Document Type and Number:
WIPO Patent Application WO/2023/243408
Kind Code:
A1
Abstract:
The present invention relates to an atropisomer represented by general formula (1) and/or general formula (2). (In formula (1) and formula (2), R1 and R2 each independently represents a structure from (R-1) to (R-20), and at least one among R1 and R2 is one from (R-1) to (R-5); however, R1 and R2 are not the same, except when the structure is (R-1).)
