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.

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.
Efficient and selective: Two lipophilic catalysts were used for Baeyer–Villiger (BV) oxidations to give lactones in high yields (see scheme). Cascadereactions involving this BV oxidation were used to selectively obtain either unsaturated carboxylic acids or hydroxylactones in high yields from β‐silyl cyclohexanones.
