Stereoselective synthesis of syn1,3-diols
Mohr, Peter
, p. 2455 - 2458 (2007/10/02)
Z-allylsilanes 1 are epoxidized by V5+/TBHP with high erythro-selectivity (up to 97:3). HF- or TBAFinduced fragmentation leads to syn-l,3-diols 3. Compound 3f can be gtransformed within two steps into a key synthon for the lactone moiety of com
