  13α-18-nor-16-Carboxamido steroids were synthesized via a palladium-catalyzed aminocarbonylation reaction of the corresponding iodoalkenes. The starting material was an unnatural 13α-16-keto steroid, obtained by a Wagner-Meerwein rearrangement of a 16α,17α-epoxide in the presence of [BMIM][BF4]. The 13α-16-keto steroid was converted to a mixture of 16-iodo-16-ene and 16-iodo-15-ene derivatives in two

  13α-18-nor-16-Carboxamido 类固醇是通过钯催化的相应碘代烯烃的氨基羰基化反应合成的。起始材料是一种非天然的 13α-16-酮类固醇，在 [BMIM][BF4] 存在下通过 16α,17α-环氧化物的 Wagner-Meerwein 重排获得。13α-16-酮类固醇通过巴顿方法分两步转化为 16-iodo-16-ene 和 16-iodo-15-ene 衍生物的混合物。使用不同的伯胺和仲胺作为亲核试剂进行甾体烯基碘化物的氨基羰基化。以良好的收率获得了产物 16-carboxamido-16-ene 和 16-carboxamido-15-ene 衍生物，并通过 (1)H 和 (13)C NMR、IR 和 MS 对其进行了表征。上述两种不饱和甲酰胺的还原产生相同的产物，17α-甲基-16α-甲酰胺-雄甾烷。

  Diols are efficient co-catalysts in guanidine catalysed condensation of ketones and aldehydes. According to quantum chemical calculations the acceleration effect can be explained by the formation of complexes of carbonyl compounds and diols held together by double H-bonding. The base/diol mixture can be separated from the product and recycled by reversible CO2 capture and release.

  二醇是胍催化的酮和醛缩合反应中的有效助催化剂。根据量子化学计算，加速效应可以通过羰基化合物和二醇通过双氢键结合在一起形成复合物来解释。碱/二醇混合物可以从产物中分离出来，并通过可逆的CO 2捕获和释放进行回收。
• Synthesis of novel 13α-18-norandrostane–ferrocene conjugates via homogeneous catalytic methods and their investigation on TRPV1 receptor activation

  13 alpha-Steroid-ferrocene derivatives were synthesized via two reaction pathways starting from an unnatural 16-keto-18-nor-13 alpha-steroid. The unnatural steroid was converted to ferrocene derivatives via copper-catalyzed azide-alkyne cycloaddition or palladium-catalyzed aminocarbonylation. 16-Azido- and 16-N-(prop-2-ynyl)-carboxamido-steroids were synthesized as starting materials for azide-alkyne cycloaddition with the appropriate ferrocene derivatives. Based on our earlier work, aminocarbonylation of 16-iodo-16-ene and 16-iodo-15-ene derivatives was studied with ferrocenylmethylamine. The new products were obtained in moderate to good yields and were characterized by H-1 and C-13 NMR, IR and MS. The solid state structure of the starting material 13 alpha-18-norandrostan-16-one and two carboxamide products were determined by X-ray crystallography. Evidences were provided that the N-propargyl-carboxamide compound as well as its ferrocenylmethyltriazole derivative are able to decrease the activation of TRPV1 receptor on TRG neurons.

• Ionic Liquid-Promoted Wagner–Meerwein Rearrangement of 16α,17α-Epoxyandrostanes and 16α,17α-Epoxyestranes

  Ionic liquids 1-butyl-3-methylimidazolium hexafluorophosphate ([bmitn](+)[PF(6)](-)) and 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim](-)(+)[BF(4)](-)) were found to promote an unusual Wagner-Meerwein rearrangement of steroidal 16 alpha,17 alpha-epolddes leading to unnatural 13-epi-18-nor-16-one derivatives as the main products. These compounds were isolated in good to excellent yields. 16 alpha-Hydroxy-Delta(13)-18-norsteroid5, the results of the usual rearrangement, were obtained as minor components of the reaction mixtures. The ionic liquid [bmim](+)[PF(6)](-) was shown to induce C-ring aromatization of 16 alpha,17 alpha-epoxyestranes due to the formation of HF, the hydrolysis product of [PF(6)](-). Increasing amounts of HF and [PO(2)F(2)](-) were detected by (19)F and (31)P NMR when the ionic liquid was reused. The structures of the steroidal products, 16-oxo-18-nor-13 alpha-steroid derivatives, 16 alpha-hydroxy-Delta(13)-18-norsteroids, and C-aromatic compounds were determined by two-dimensional NMR techniques and high-resolution mass spectrometry (HRMS). The ionic liquids were recirculated efficiently.
