One- and two-directional iterative 1,2-asymmetric induction in acyclic systems—easy access to anti,anti and anti,syn dipropionate and diphenylacetate stereotriads
摘要:
Stereocontrolled addition of organocuprate reagents to gamma-alkoxy-alpha,beta-unsaturated esters can be done in one- and two-directional modes with excellent 1,2-induction. Enolate hydroxylations proceed with high diastereoselectivity affording acyclic chains with three to five contiguous stereogenic centers of the propionate and phenylpropionate triad types.
