in Saccharomyces cerevisiae produced cladosporin, confirming the identity of the putative gene cluster. Incorporation of a pentaketide intermediate analogue indicated a 5+3 assembly by the HR PKS Cla2 and the NR PKS Cla3 during cladosporinbiosynthesis. Advanced‐intermediate analogues were synthesized and incorporated by Cla3 to furnish newcladosporinanalogues. A putative lysyl‐tRNA synthetase resistance

Glycerol may be simultaneously protected and enantioselectively desymmetrised by dispiroketal formation with (S,S)-2,2′-dimethyl-3,3′,4,4′-tetrahydro- 6,6′-bi-2H-pyran 1.

A highly enantioselective Michael addition reaction of alkyl selenols to enones is reported. The development of a chiral bifunctional N-heterocycliccarbene (NHC)/thiourea catalyst was key in obtaining the chiral β-seleno ketones with remarkable selectivity.

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.
