The intermolecular oxypalladation of chiral nonracemic allylic alcohols (S)-1, (R)-1, and (R)-3 in methanol gave chiral nonracemic methyl allyl ethers (S)-2 and/or (R)-2 with excellent selectivity. The reaction induced the 1,3-chirality transfer to give syn-SN2′ product exclusively through syn oxypalladation. On the other hand, the anti-SN2′ product was produced in 20−33% in THF, toluene, and CH2Cl2
