SYNTHESIS OF NONRACEMIC γ-ALKOXY ALLYLSTANNANES BY STEREOSPECIFIC ANTI-STANNYL MIGRATIONON
Marshall, James A.,Gung, Wei Yi
, p. 2183 - 2186 (2007/10/02)
The γ-alkoxy allylstannane 5b, prepared in high yield by BF3*OEt2 promoted rearrangement of the (S)--α-alkoxy allylstannane 4b, affords the syn 1,2-diol derivatives 8 and 9 in high yield and excellent ee upon condensation with various aldehydes.
