Chemoenzymatic synthesis of a versatile cyclopentenone: (+)-(3aS,6aS)-2,2-dimethyl-3aβ,6aβ-dihydro-4H-cyclopenta-1,3-dioxol-4-one

Add time:07/12/2019    Source:sciencedirect.com

The title cyclopentenone has been prepared by enzymatic resolution of cis-4-phenyloxy- and cis-4-(4-methoxyphenyloxy)-cyclopent-2-en-1-ol in isopropenyl acetate using Pseudomonas cepacia lipase. The use of a 4-methoxyphenyloxy-alcohol intermediate enabled the use of both enzymatically resolved enantiomers in the synthesis of the desired (+)-enone.
