Abstract
In this paper, we have established an operationally convenient protocol for the rapid construction of polysubstituted methyleneindene and quinoline derivatives under mild conditions. This new synthetic method is achieved through the conversion of acetyl-substituted methylenecyclopropanes with TsOH ⋅ H2O and ortho-amino-substituted methylenecyclopropanes with aromatic aldehyde and TsOH ⋅ H2O, respectively. A variety of transformations of the obtained products was demonstrated. The plausible reaction mechanisms were also proposed.

Abstract
Sequential Knoevenagel condensation/cyclization leading to indene and benzofulvene derivatives has been developed. The reaction of 2-(1-phenylvinyl)benzaldehyde with malonates gave benzylidene malonates, cyclized indenes, and dehydrogenated benzofulvenes. The product selectivity depends on the reaction conditions. The reaction with piperidine, AcOH in benzene at 80 °C for 1.5 h gave a benzylidene malonate in 75% yield as a major product. The reactions with piperidine, AcOH in benzene at 80 °C for 17 h and with TiCl4-pyridine at room temperature gave an indene derivative in 56 and 79% yields, respectively, as a major product. The reaction with TiCl4-Et3N gave a benzofulvene in 40% yield selectively. Indene was transformed to a benzofulvene derivative using the reagents TiCl4-Et3N and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). The reaction of variously substituted aryl derivatives with dimethyl malonate gave indene and benzofulvene derivatives. The reactions of 2-(1-phenylvinyl)benzaldehyde with Meldrum's acid or malononitrile also gave cyclized compounds in the suitable sequential or stepwise conditions. Furthermore, the reaction of 2-arylbenzaldehydes has been investigated. The limitation and scope have been described. The reaction mechanism of the cyclization steps has been examined by DFT calculations.

Int J Biochem Cell Biol 2016; 81:57-66.

Abstract
PPARγ agonists induced obesity in animal models as a side effect. Microarray experiments reveal that PPARγ agonist upregulates the expression of lipin-1 and this upregulation is correlated with the activity of the agonists. Lipin-1 induced by PPARγ agonists decreased the levels of PPARγ and ERK1/2 phosphorylation through direct interaction with these proteins in 3T3-L1 cells. In PPARγ agonist-treated 3T3-L1 preadipocytes, the knockdown of lipin-1 expression by small interfering RNA inhibited the adipogenesis that was induced by PPARγ agonists. In contrast, PPARγ2 expression was increased, and lipid droplets were accumulated in lipin-1-overexpressing 3T3-L1 adipocytes. Rosiglitazone (RGZ), a strong PPARγ agonist, synergistically promoted PPARγ dephosphorylation and adipogenesis in lipin-1-overexpressing 3T3-L1 preadipocytes. Therefore, lipin-1 has dual functions as a transcriptional cofactor and phosphatidate phosphatase (PAP) in the differentiation of preadipocyte cells induced by strong PPARγ agonists. In addition, the adipogenesis of 3T3-L1 cells was markedly upregulated by diacylglycerol (DAG), which was produced by lipin-1. Therefore, lipin-1 induction by PPARγ agonists might be an important factor in understanding the biological mechanism of the agonists' adverse effects, and this information may be valuable in the development of type-2 diabetes mellitus (T2DM) therapeutics with reduced adverse effects and greater tolerability.

Abstract
A synthetic method to chemoselectively prepare 1H-cyclopenta[b]naphthalenes, cis-cyclopenten-2-yl δ-diketones, and bicyclo[3.2.0]hepta-1,5-dienes efficiently by gold-catalyzed cycloisomerization of 1,6-diyne esters is described. These three product classes were accessed divergently by taking advantage of the electronic and steric differences between a phosphine and NHC (NHC = N-heterocyclic carbene) ligand in the respective gold(I) complexes and that of gold(III) complex combined with substrate substitution patterns and optimized reaction conditions. In the presence of [PhCNAuIPr](+)SbF6(-) (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidine) as the catalyst, substrates with a pendant aryl group at the acetate alkynyl position were found to undergo preferential 1,3-acyloxy migration/5-exo-dig cyclization/Friedel-Crafts reaction to give 1H-cyclopenta[b]naphthalenes. In contrast, the analogous reactions with PicAuCl2 (Pic =2-picolinate) were found to proceed by selective 1,3-acyloxy migration/5-exo-dig cyclization/1,5-acyl migration to afford cis-cyclopenten-2-yl δ-diketones. Changing the catalyst to [MeCNAu(JohnPhos)](+)SbF6(-) (JohnPhos = (1,1'-biphenyl-2-yl)-di-tert-butylphosphine) and the acetate alkynyl position from an aryl to vinyl substituent in the starting ester led to 1,3-acyloxy migration/5-exo-dig cyclization/Prins-type [2 + 2]-cycloaddition to provide bicyclo[3.2.0]hepta-1,5-dienes.
