The first total synthesis of Goniothalesdiol A, isolated from the stems of Goniothalamus amuyon (Annonaceae) is reported. The C2 stereocentre and C3/C4 syn diol were created by a Sharpless kinetic resolution followed by acetonide formation. The tetrahydropyran ring was formed and the C6 stereocentre
## Abstract The stereocontrolled synthesis of goniothalesdiol A, a dihydroxylated tetrahydropyran compound, has been accomplished using D‐ribose as chiral precursor. The key steps involved are aryl __Grignard__ reaction, stereoselective alkoxy‐directed keto reduction, and intramolecular oxy‐__Micha
## Abstract Good to excellent stereoselectivities were achieved in the reductive cyclization (with Et~3~SiH/trimethylsilyl trifluoromethanesulfonate (TMSOTf)) of enantiopure hydroxy sulfinyl ketones en route to 2,5‐__cis__‐disubstituted tetrahydrofuran skeletons. Electrostatic effects of the exocyc
The first total synthesis of goniothalesdiol, a dihydroxylated tetrahydrofuran isolated from Goniothalamus borneensis (Annonaceae), and its 7-epimer is described starting with D-mannitol. The key step of these syntheses is palladium(II)-catalyzed oxycarbonylation of unsaturated triols with D-lyxo an
