Rhenium complex-catalyzed allylation of acetals with allyltrimethylsilane
摘要:
It was confirmed that the treatment of acetals with allyltrimethylsilane in the presence of a catalytic amount of the rhenium complex, ReBr(CO)(5), gave the corresponding homoallylic ethers in excellent to good yields. (C) 2008 Elsevier Ltd. All rights reserved.

modified by chiralalcohols, forming chiral aluminum reagents (∗ROH/AlCl3). ∗ROH/AlCl3 was used to promote asymmetricallylation of aldehydes with etherification by allyltrimethylsilane, giving the chiralhomoallylic ethers in good yields and good to excellent de (51–93%). The monoalkoxy aluminum (∗RO)AlCl2, generated in situ was determined as an active and stereogenic species in one pot allylation reaction
