Gold-catalyzed oxidative reactions of propargylic carbonates involving 1,2-carbonate migration: Stereoselective synthesis of functionalized alkenes
Sun, Ning,Chen, Ming,Liu, Yuanhong
, p. 4055 - 4067 (2014/05/20)
A gold-catalyzed oxidative reaction of propargylic carbonates or acetates using 3,5-dichloropyridine as the oxidant has been developed. The reaction provides efficient access to α-functionalized-α,β-unsaturated ketones with excellent regio- and diastereoc
Palladium-catalyzed coupling of propargylic carbonates with N-tosylhydrazones: Highly selective synthesis of substituted propargylic N-sulfonylhydrazones and vinylallenes

An efficient palladium-catalyzed coupling of propargylic carbonates (1) with N-tosylhydrazones (2, 2′) has been carried out. A wide range of propargylic N-sulfonylhydrazones (3) and multisubstituted vinylallenes (4) can be obtained selectively by using either [PdCl2(CH3CN) 2] or [Pd2(dba)3] as catalysts.

, p. 13929 - 13942 (2007/10/03)
The palladium catalyzed cross-coupling reaction of trialkyl(indol-2- yl)borates with prop-2-ynyl carbonates was developed for the preparation of 2-allenylindole derivatives. When the reaction of indolylborates with tert- prop-2-ynyl carbonates was carried
