Hydroxylation of olefins using molecular oxygen via alkylboronic esters
摘要:
Alkylboronic esters derived from olefins undergo a hydroxylation in the presence of triethylamine and molecular oxygen. Alcohols were obtained in good to excellent yields without alkaline treatment of the boronate ester intermediates. Radical-clock experiments allowed the comparison between radical and polar reaction paths. (C) 2001 Elsevier Science Ltd. All rights reserved.
