Ja. Marshall et al., STEREOSELECTIVE SYNTHESIS OF LONG-CHAIN POLYOLS BY SEQUENTIAL HOMOLOGATION OF ENALS WITH NONRACEMIC GAMMA-SILYLOXY ALLYLIC STANNANES AND DIRECTED HYDROXYLATION, Journal of organic chemistry, 58(22), 1993, pp. 5876-5877
The nonracemic gamma-silyloxy allylic stannanes (S)-8 and (R)-8 add to
the (R,R)-tartrate derived enals 7 and 24 to afford the adducts 9, 14
, and 25. The bis-TBS derivatives 10, 15 and 22, upon hydroxylation wi
th catalytic 0804-NMO, yield the differentially protected polyols 11,
16, and 23.
