One-Pot Asymmetric Synthesis of 2- and 2,3-Disubstituted Tetrahydrofuran Derivatives
摘要:
A novel and convenient one-pot asymmetric synthesis of 2- and 2,3-disubstituted tetrahydrofurans has been achieved in 56-81% yields and 86-99% ee from aliphatic and aromatic aldehydes via an allyl/crotyl/alkoxyallylboration-hydroboration-iodination-cyclization reaction sequence.
Chiral synthesis via organoboranes. 13. A highly diastereoselective and enantioselective addition of [(Z)-.gamma.-alkoxyallyl]diisopinocampheylboranes to aldehydes
