B. Crousse et al., STEREOSELECTIVE REDUCTION OF CONJUGATED HOMOPROPARGYLIC ALCOHOLS TO (E)-HOMOALLYLIC ALCOHOLS BY SODIUM BIS(2-METHOXYETHOXY) ALUMINUM-HYDRIDE, Synlett, (8), 1997, pp. 992
The reduction of various conjugated homopropargylic alcohols with sodi
um bis(2-methoxyethoxy) aluminium hydride (Red-Al(R)) in ether or THF
is described. The reaction takes place cleanly and rapidly, under mild
conditions, to give (E)-homoallylic alcohols stereoselectively in goo
d isolated yields.
