Convergent synthesis of potent COX-2 inhibitor inotilone
Shamshina, Julia L.,Snowden, Timothy S.
, p. 3767 - 3769 (2007)
The first synthesis of potent COX-2 inhibitor inotilone is reported. The convergent route features a Mukaiyama aldol condensation that generates the target without the use of protecting groups or a separate dehydration step. The approach also highlights a

An NADPH-dependent reductase that shows reducing activity for 1-chloro-2-hexanone has been purified from bakers' yeast. SDS-PAGE and gel filtration suggested that the purified reductase is a monomeric enzyme with a molecular weight of ca. 37 kDa. Asymmetric reduction of several carbonyl compounds using the purified reductase has been carried out. 1-Chloro-2-hexanone, 1-acetoxy-2-heptanone, methyl acetoacetate, ethyl pyruvate, 1-chloro-2,4-pentanedione, and 2,4-hexanedione were reduced to the corresponding alcohols with high enantiomeric purities (>98% ee). The reductase showed high specificity constants (kcat/Km = 103-105 s-1 M-1) and relatively low Michaelis constants (Km = 10-4-10-3 M) for all the substrates examined.
Stereochemical Determination of Tuscolid/Tuscorons and Total Synthesis of Tuscoron D and E: Insights into the Tuscolid/Tuscoron Rearrangement

The stereochemistry of the structurally unique myxobacterial polyketides tuscolid/tuscorons was determined by a combination of high-field NMR studies, molecular modeling, and chemical derivatization and confirmed by a modular total synthesis of tuscorons D and E. Together with the discovery of three novel tuscorons, this study provides detailed insight into the chemically unprecedented tuscolid/tuscoron rearrangement cascade.
Inotilone derivatives as coherent biological response modifier (cBMR)

, (2011/04/14)
Optimal compositions of derivatives of 5-methyl-3(2H)-furanone compounds and phenylpropanoid polyketides related to inotilone, that exert biological response modification in health and disease, and their method of preparation, are disclosed. Methods of tr
Short synthesis of COX-2 inhibitor inotilone

experimental part, p. 1088 - 1092 (2010/05/18)
An efficient three-step synthesis of COX-2 inhibitor inotilone from acetaldoxime is described. The structure of inotilone was elucidated via an aldol reaction between 5-methyl-3(2H)-furanone and 3,4-dihydroxybenzaldehyde. This approach describes a convenient pathway to 5-alkyl-3-furanones through isoxazole chemistry.
