Efficient one-step synthesis of chiral bidentate oxazoline-alcohol ligands via a cyclic imidate ester rearrangement
摘要:
Various chiral bidentate oxazoline-alcohol ligands were obtained in a straightforward one-step synthesis via a cyclic imidate ester rearrangement. These chiral ligands were tested and compared in asymmetric diethylzinc additions to aldehydes resulting in selectivities of up to 87% ee. An interesting chirality switch was observed when a CPh2-tether instead of a CH2 was present, offering the opportunity for dual stereocontrol. (C) 2009 Elsevier Ltd. All rights reserved.

日期:2021.3.19
A palladium-catalyzed tandem carbonylative lactonization and Diels–Alder cycloaddition reaction between aldehyde-tethered benzylhalides and alkenes has been developed. A range of alkenes and aldehyde-tethered benzylhalides bearing different substituents can be successfully transformed into the corresponding bridged polycyclic compounds in good yields. This strategy provides a unique approach to complex

The activation of 2-(bromomethyl)benzaldehydes using N-heterocyclic carbenes represents a novelapproach to the generation of o-quinodimethane (o-QDM) intermediates. Coupling with ketones such as phenylglyoxylates, isatins, or trifluoromethyl ketones via [4 + 2] annulation gives access to functionalized 1-isochromanones.
