Zeise’s dimer-catalyzed regioselective hydration of homopropargyl tertiary ether
摘要:
The regioselective hydroalkoxylation of homopropargyl tertiary ether catalyzed by Zeise's dimer was realized. The desired products were obtained in 61-95% yield with good regioselectivity. This methodology represents a valuable alternative to the aldol reaction or the oxa-Michael reaction to form prochiral tertiary beta-hydroxy ketones. (C) 2012 Elsevier Ltd. All rights reserved.

Ruthenium–catalyzedenyne metathesis is a reliable and efficient method for the formation of 1,3-dienes, a common structural motif in synthetic organic chemistry. The development of new transition-metal complexes competent to catalyze enyne metathesis reactions remains an important research area. This report describes the use of ruthenium (IV) dihydride complexes with the general structure RuH2Cl2(PR3)2
