Model compounds (11 and 12) for the C1-C10 tetrahydropyran fragment of amphidinol 2 were prepared from (2S)-benzyloxypropanal in 9 steps. The synthetic route relied on diastereoselective diene-aldehyde cycloaddition, stereoselective C-allylation, and reagent based enantioselective aldehyde allylatio
The relative configuration of a methylated undecanehexaol, a fragment of amycin B, with five chirality centers was determined by a complete 1 H and 13 C signal assignment and interpretation of its acetonide derivatives.
A synthesis of the C(1) C( 16) fragment 43 of the bryostatins is reported which features a stereoselective equivalent of an 'ene' reaction between the allylsilane 35 and the alkynone 33 and the stereoselective conjugate addition-cyclisation of the dienyl ketone 36 to give the acetal 39 after acetali
