Dialkyl-substituted terminal olefins were synthesized from the coupling reaction of αt-olefins which were catalyzed by zirconocene dichloride/methylalumoxane (
Lithium aluminium amide [LiAl(NHR)4] 5 obtained by treating the primary amine 4 with LiAlH4 could promote the ring opening of epoxide 2 and led to high regiosel
Phenyl bonded mesoporous silica (C6H5-MCM-41) was applied as the fiber coating of solid-phase microextraction (SPME). The performance of the fiber coating was d
In this paper, two new compounds, ent-16α-hydroxy-15β-hydroxymethylbeyeran-19-oic acid 4 and its ethyl ester 5 were synthesized in good yield with a facile me
