We studied the canonical structure of 2D $F(R)$ gravity. Its equivalence withJackiw-Teitelboim gravity is demonstrated when no matter presents. Then, due toAdS$_2$/CFT$_1$ correspondence, such $F(R)$ gravity is equivalent to theSachdev-Ye--Kitaev models. The singular $D\to 2$ limit of $F(R)$ gravity isalso studied. It is shown that in such a limit AdS$_2$/CFT$_1$ correspondenceis not realized.
