The first asymmetric total syntheses of cladosporin and isocladosporin were accomplished in 8 steps with 8% overall yield and 10 steps with 26% overall yield, respectively. The relative configuration of isocladosporin was determined via this totalsynthesis.

A convergent total synthesis of isocladosporin and 3-epi-isocladosporin is reported starting from commercially available homoallyl alcohol in 10 longest linear steps with 28% overall yield. The key steps involved in the synthesis are cross-metathesis, tandem isomerization followed by C-O and C-C bond formation reactions for the synthesis of trans-2,6-disubstituted dihydropyrans developed by us, acylation reaction and Luche reaction.
