The use of a chemoenzymatic approach also gave (-)-6-epi-cleistenolide (1) (&amp;gt;99.9% ee). The Achmatowicz reaction, chemoselective oxidation of a hemiacetal, diastereoselective 1,3-anti reduction of alpha-hydroxy ketone, and enzymatic resolution of a 1,3-diol are the key features of this linear total synthesis. The synthetic strategy demonstrated in this paper could be extended for an asymmetric total synthesis of (-)-cleistenolide (1) and related biologically active natural products.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">36</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">3.13</style></custom4></record></records></xml>
