Key HMBC (arrow) and COSY (bold) correlations of 2
The absolute configuration of the asymmetric carbon C-2 in compounds 1–6 is proposed to be (R), analogous to that of monocillin IV (1) due to the same optical activity sign and comparison with the X-ray data of compound 1. However, the structure for compounds 1–6 was drawn incorrectly as (S) configuration in C-2, in our paper. We apologize for any inconvenience caused by these errors.
