Diastereoselective Synthesis of Protected 1,3-Diols by Catalytic Diol Relocation
摘要:
A complementary diastereoselective gold(I) or bismuth(III) catalyzed tandem hemiacetalization/dehydrative cyclization of 1,5-monoallylic diols was developed to access 1,3-dioxolanes and dioxanes. This methodology provides rapid access to protected 1,3-diols under mild conditions with high levels of diastereoselectivity.
