Sarkomycin A methyl esters and functionalized cyclopentane blocks for brefeldin A
摘要:
Sarkomycin A methyl esters and functionalized cyclopentane blocks for brefeldin A were synthesized starting from diastereoisomeric (1R,2S)- and (1S,2R)-2-hydroxymethyl-N-[(1R)-1-phenylethyl]cyclopent-3-ene-1-carboxamides.
Epoxy derivatives of {(5-[(1-Phenylethyl)aminocarbonyl]-cyclopent-2-en-1-yl}methyl acetates
摘要:
Diastereoisomeric [(1R,5S)-5-{[(1R)-1-phenylethyl]aminocarbonyl}cyclopent-2-en-1-yl]methyl acetate and [(1S,5R)-5-{[(1R)-1-phenylethyl]aminocarbonyl}cyclopent-2-en-1-yl]methyl acetate reacted with m-chloroperoxybenzoic acid to give the corresponding stereoisomeric alpha- and beta-epoxy derivatives, which were identified on the basis of their spectral parameters.
