摘要:
The catalytic osmylation of enantiomerically enriched (E)-crotylsilanes (2S,3R)-1 and (2R,3R)-2 containing a homoallylic, nitrogen-bearing stereocenter proceeds with good to high levels of diastereoselection generating silyl-functionalized trans-4,5 substituted gamma-lactones 3 and 5 as the major diastereomers.
