Stockdale, Tegan P. published the artcileA synthesis-enabled relative configurational assignment of the C31-C46 region of hemicalide, HPLC of Formula: 99438-28-5, the publication is Chemical Communications (Cambridge, United Kingdom) (2022), 58(38), 5729-5732, database is CAplus and MEDLINE.
Herein, through the targeted synthesis of configurationally defined fragments, as well as “encoded” mixtures of diastereomers, the stereochem. elucidation of the C31-C46 region of hemicalide I was achieved. Detailed NMR spectroscopic anal. of candidate fragments and comparison with the related hemicalide data strongly supported a 31,32-syn, 32,36-anti and 42,46-anti relationship. In combination with previous work on hemicalide, this reduced the number of possible structural permutations down to a more manageable eight diastereomers.
