The addition of allyltitanium reagents, generated by the desulfurizative titanation of allylic sulfides with the titanocene(II) reagent Cp 2Ti-1-butene, to α-chiral ketones produced tertiary homoallylic alcohols bearing three adjacent chiral ce

(Chemical Equation Presented) A concise and stereoselective synthesis of the tetrasubstituted tetrahydropyran core of polycavernoside A was achieved in 55% overall yield from 3-benzyloxypropanal. A stereoselective allyl transfer reaction was used in the synthesis of enol ether 18 followed by a TFA-mediated cyclization to create the three new asymmetric centers in the tetrahydropyran with complete stereocontrol in a single-pot process.

Enantiopure homoallylic alcohols such as 1 (conveniently prepared from alk-2-enyl metal reagents with (-)- or (+)-menthone) serve as alk-2-enyl donors to aldehydes. The allyl-transfer reaction, which proceeds via a chairlike six-membered-ring transition s
