Abstract
The stereoselective synthesis of 1, 3-dioxygenated compounds is important from the synthetic point of view, since these fragments appear in the structure of various natural products. 2 The reduction of β-hydroxy ketones to syn 1, 3-diols is usually carried out via an intermolecular hydride shift using several stoichiometric reducing agents, such as (n-Bu) 3B- NaBH4, 3 Et2BOMe-NaBH4, 4 terphenylboronic acid-NaBH4, 5 Ti (OPri) 4-NaBH4, 6 ...
