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.

Diastereomeric amides produced via the decomposition of easily available (+/-)-7,7-dichlorobicyclo[3.2.0]hept-2-en-6-one by treatment with (+)- or (-)-alpha-methylbenzylamines were transformed into bicyclic lactam-aminals, which can easily be separated using the column chromatography on SiO2. The latter products lead to enantiomeric 3-oxabicyclo[3.3.0]oct-6-en-2-ones after the removal of the chiral auxiliary. Crown Copyright (C) 2008 Published by Elsevier Ltd. All rights reserved.
