WEI Meng-xue, MA Chao, XU Jian, ZHANG He, LI Xue-qiang
DOI: 10.15952/j.cnki.cjsc.1005-1511.2015.10.0893
A piperazine-amide derivative(
2
) was obtained by one-pot method, using dihydroartemisinin（DHA）, oxalyl chloride and piperazine as materials. Six novel piperazine-aliphatic amide derivatives（
4a
～
4f
） were synthesized by acylation of
2
with aliphatic acyl chloride．The structures were characterized by
1
H NMR,
13
C NMR, IR and HR-ESI-MS. The anti-cancer activities
in vitro
of
4a~4f
against human hepatoma SMMC-7721 cell lines were investigated by MTT method. The preliminary bioassay results showed that 4a～4f inhibited the proliferation and induced the apoptosis of SMMC-7721. Especially dihydroartemisinin piperazinechlorine acetamide（
4c
)
had the best inhibition activity against SMMC-7721 with IC
50
0.05 μM, which was superior to artemisinin（IC
50
0.53 μM） and DHA（IC
50
0.52 μM）.

DOI: 10.15952/j.cnki.cjsc.1005-1511.2015.10.0899
Six new amide-multifunctionalized ionic liquids(
2a～2c
，
3a~3c
) were obtained by ion exchange of KPF-6 with 1-methyimidazole（or imidazole） and
N-
aryl-3-chlorobutanamide. The conversion and regioselectivities were investigated by the Heck reaction of 2-bromo-6-methoxynaphthylene with allyl alcohol using
2
or
3
as the medium. The results showed that the conversion and regioselectivities in
3
was better than in
2
. Substituted aryl allyl alcohols were synthesized with high yields（85％～89%） and regioselectivities（＞99％） by Heck reaction of haloaryl compounds with allyl alcohol, using
3c
as the medium and palladium acetate as the catalyst. The structures were characterized by
1
H NMR,
13

DOI: 10.15952/j.cnki.cjsc.1005-1511.2015.10.0974
Poly(
p
-dioxanone)(PPDO) was synthesized by ring-opening polymerization reaction of
p
-dio-xanone. Non-isothermal crystallization behavior of PPDO was investigated by DSC. The non-isothermal crystallization was analyzed by Ozawa equation in detail. And the non-isothermal cold crystallization of PPDO was analyzed by the Mo method.

The reaction of
N
-substituted benzylcarbazoles(or
N
-substituted benzylindoles) with potassium tert-butoxide resulted in debenzylation to carbazole（or indole） in oxygen． The yields were 68%~94％(or 75%~89%). The structures were confirmed by
1
H NMR and
13
C NMR.

Sixteen novel 1
H
-［1,2,3］triazole［4,5-
c
］pyridazine compounds were synthesized from aromatic amine， iodomethane， tert-butyl 4-［(methylsulfonyl)oxy］piperidine-1-carboxylate and 2-(2-bromoethoxy)tetrahydro-2
H
-pyran by substitution, oxidization and Suzuki reaction， using 3,4,6-trichloropyridazine and 4-iodo-1
H
-pyrazole as starting materials. The structures were characterized by
1
H NMR and ESI-MS.

-Eucryptite
ZHANG Wei
DOI: 10.15952/j.cnki.cjsc.1005-1511.2015.10.0985
The main synthetic methods of
β
-eucryptite including solid state reaction at high temperature, low-temperature combustion synthesis, sol-gel, polymer-network gel and glass crystallization， were reviewed with 53 references. The advantages and disadvantages of the methods were briefly summarized.
