The method of the present invention comprises the following steps: reacting a diester compound under the action of an enzyme to obtain a monoester compound; subjecting the resulting monoester compound to a sulfonation reaction and then to a reaction with a compound such as boroxine, such that multiple drugs or drug intermediates with a single configuration can be prepared. The method of the present invention by which the ee value of the monoester compound obtained may exceed 40% favors the preparation of compounds with high optical purity and cost control.

Title: Valve clamp and valve clamping system
Inventor: ZHANG TINGCHAO
IPC: A61B17/122
Filed: 2019-05-09
Abstract: A valve clamp (100, 200) and a valve clamping system. The valve clamping system comprises a valve clamp (100, 200) and a push device. The valve clamp (100, 200) comprises a push rod (40), at least two clamps (10), and at least one extension arm (20). Each of the clamps (10) comprise a first clamping arm (11) able to open and close relative to another clamp arm, and at least one extension arm (20) is telescopically disposed on a surface of the first clamping arm (11). Providing the telescopic extension arm (20) on the surface of the first clamping arm (11) of the valve clamp (100, 200) and causing the extension arm (20) to extend out of the first clamping arm (11) while the first clamping arm (11) opens relative to the push rod (40) of the valve clamp (100, 200), is equivalent to increasing the length of the first clamping arm (11) of the clamp (10), so that the longer first clamping arm (11) can better support a valve leaflet when capturing the valve leaflet, preventing the leaflet from slipping off the surface of the first clamping arm (11), thereby rapidly capturing an active valve leaflet, reducing surgical difficulty, and improving surgical efficiency.
