WebApr 15, 2024 · Epoxide hydrolases are attractive and industrially important biocatalysts. They can catalyze the enantioselective hydrolysis of epoxides to the corresponding diols as chiral building blocks for bioactive compounds and drugs. In this review article, we discuss the state of the art and development potential of epoxide hydrolases as biocatalysts …

Did you know?
WebCompounds C, D & H have more than one chiral center, and are also chiral. Remember, all chiral structures may exist as a pair of enantiomers. Other configurational stereoisomers are possible if more than one stereogenic center is present in a structure. WebThe major ion in the chromatogram is the m / z 342. This ion is the result of a single TMS derivative to the estrone structure. Notice that the carbonyl group is not derivatized by the BSTFA, which is an expected result. The m / z 342 is chosen then as the precursor ion for estrone for the MRM transitions.
