Synthesis of the C1−C21 (C1‘-C21‘) Fragment of the Dimeric Polyketide Natural Product SCH 351448
Organic Letters, 2002[structure: see text] A convergent, stereoselective assembly of the C1-C21 (C1'-C21') fragment of SCH 351448, a 28-membered bis-lactone natural product, has been developed. A highly efficient approach to this fragment assembles 75% of the carbon skeleton and all the stereochemical elements present in the natural product.

C21 steroids from the roots of Marsdenia tenacissima
Phytochemistry, 2023A phytochemical investigation of the dichloromethane soluble fraction of the ethanolic extract obtained from the roots of Marsdenia tenacissima led to the discovery of the sixteen undescribed pregnane C21 steroids (1-16) and isolation of eleven known C21 steroidal analogues (17-27).

Electronic spectra of long odd-number carbon chains C17–C21 and C13−–C21−
Chemical Physics Letters, 1999Abstract Electronic transitions of the odd-number neutral and anionic carbon chains C2n+1 (n=8–10) and C2n+1− (n=6–10) have been observed in a neon matrix at 6 K after co-deposition with laser-vaporized graphite. The assignments are based on a comparison with the previously identified electronic transition of C7 to C15 and C5− to C11−, and the ...

Production of C21 steroids in rat fetal ovaries
Journal of Steroid Biochemistry, 1988Female gonads of fetal and neonatal rats were cultured for 24 h in medium 199 supplemented with dibutyryl cyclic AMP (dcAMP), cycloheximide, spironolactone (an inhibitor of 17 alpha-hydroxylase) or hydroxylated cholesterol derivatives. Radioimmunoassays of pregnenolone (P5) and progesterone (P4) were performed in the media.
