Hot water was believed to act as a mild Bronsted acid catalyst in the epoxide-opening reactions.展开更多
Allylalumination of alkynes (i.e. forming Negishi's (Z)-alkenyl dialkylalane) followed by alkenylation of epoxides provides 1,4-disubstituted (Z)-3,6-alkadienols. The alkenylation can be facilitated by the pres...Allylalumination of alkynes (i.e. forming Negishi's (Z)-alkenyl dialkylalane) followed by alkenylation of epoxides provides 1,4-disubstituted (Z)-3,6-alkadienols. The alkenylation can be facilitated by the presence of a neighbouring coordinating group in the epoxides. This "one-pot" approach has been successfully applied in the large-scale production of C 10--C 15 fragment of 9,10-didehydroepothilone D (a synthetic epothilone analog as an anti-cancer agent in phase 2 clinical trials).展开更多

A new 2D coordination polymer, [Cd(tpim)(1,5-nds)]n (1), was constructed from 1,5-naphthalenedi- sulfonate (1,5-nds). 2.4,5-tri(4-pyridyl)-imidazole (tpim) and Cd(CH3COO)2.2H2O, which can be subsequently...A new 2D coordination polymer, [Cd(tpim)(1,5-nds)]n (1), was constructed from 1,5-naphthalenedi- sulfonate (1,5-nds). 2.4,5-tri(4-pyridyl)-imidazole (tpim) and Cd(CH3COO)2.2H2O, which can be subsequently used to promote the epoxide ring-opening reaction of epoxides and amines with remarkable catalytic activity. In addition, the thermal and luminescent properties of I in the solid state were also investigated.展开更多
