Here, we first report the 2′-acyloxy-1,3-dicarbonyl compound construction in a three-component oxidative reaction of alkyl ketene dimer with cyclic diacyl peroxide and trimethyl orthoformate. The discovered synthesis allows us to form 2′-functionalized 1,3-dicarbonyl compounds instead common 2-functionalized moiety. between 4-butylidene-3-propyloxetan-2-one cyclopropyl malonoyl proceeds presenc...

Phosphonate derivatives were prepared using multicomponent reactions of dialkyl acetylenedicarboxylate with 4-hydroxycumarine in the presence of trimethyl or triphenyl phosphite in good yields.

In the crystal structure of the title compound (N4CPSTMAA), C(11)H(14)ClNO(3)S, the conformations of the N-H and C=O bonds in the amide group are anti to each other, similar to those observed in N-phenyl-sulfonyl-2,2,2-trimethyl-acetamide (NPSTMAA) and 2,2,2-trimethyl-N-(4-methyl-phenyl-sulfon-yl)acetamide (N4MPSTMAA). The bond parameters in N4CPSTMAA are similar to those in NPSTMAA, N4MPSTMAA,...

In the title complex, [Sn(C(2)H(2)ClO(2))(2)(C(4)H(11)Si)(2)], the Sn(IV) ion is coordinated in a distorted tetra-hedral environment formed by two O atoms from two monodenate chloro-acetato ligands and two C atoms from two trimethyl silyl ligands. Two further weak intra-molecular Sn⋯O contacts [2.744 (2) and 2.655 (2) Å] are formed by the chloro-acetato ligands.

The title compound, C(14)H(19)N(2) (+)·BF(4) (-), was obtained by reaction of 1-ethyl-3-(2,4,6-trimethyl-phen-yl)imidazolium tetra-fluoro-borate with sodium tetra-fluoro-borate. The imidazole ring makes a dihedral angle of 78.92 (13)° with the benzene ring.

We synthesized 2-arachidonoylglycerol (1), an endogenous cannabinoid receptor ligand, and its metabolically stable ether-linked analogues. Compound 1 was synthesized from 1,3-benzylideneglycerol (6) and arachidonic acid in the presence of N,N'-dicyclohexylcarbodiimide and 4-dimethylaminopyridine followed by treatment with boric acid and trimethyl borate. An ether-linked analogue of 2-arachidono...
