Reaction of lithium eneselenolates derived from selenoamides with ketones: a highly diastereoselective synthetic route to β,β-disubstituted β-hydroxy selenoamides
摘要:
The reaction of lithium eneselenolates generated from selenoamides with a variety of ketones proceeded smoothly at -78degreesC to give the corresponding beta,beta-disubstituted beta-hydroxy selenoamides in moderate to good yields. The reaction showed high diastereoselectivity. The products obtained were converted to the corresponding amides by reacting them with cyclohexene oxide. (C) 2003 Elsevier Science Ltd.

Under (not so much) pressure: A general method for the hydrogenation of tertiary and secondary amides to amines with excellent selectivity using a bimetallic Pd–Re catalyst has been developed. The reaction proceeds under low pressure and comparatively low temperature. This method provides organic chemists with a simple and reliable tool for the synthesis of amines.

Herein, we disclose that electrochemical stimulation induces new photocatalytic activity from a range of structurally diverse conventional photocatalysts. These studies uncover a new electron-primed photoredox catalyst capable of promoting the reductive cleavage of strong C(sp2)−N and C(sp2)−O bonds. We illustrate several examples of the synthetic utility of these deeply reducing but otherwise safe
