Description / Table of Contents:
Diastereoselektive Addition von Crotylboronsäureestern an OximeAddition der E-sowie Z-Crotylboronsäureester 8, 9 an Aldoxime ließ sich unter 4-9 kbar Druck in guten Ausbeuten realisieren. Dabei resultierte eine der Richtung nach überraschende Diastereoselektivität: E-8 ergab bevorzugt die anti-, Z-9 die syn-N-(β-Methylalkyl)hydroxylamine 10, 11.
Notes:
The addition of E-and Z-crotylboronates 8, 9 to aldoximes has been realized in good yields by running the reaction under 4-9 kbar pressure. The direction of the attendant diastereoselectivity was surprising: E-8 led preferentially to the anti-, Z-9 to the syn-N-(β-methylalkyl)hydroxylamines 10, 11.
