  Microwave assisted preparation of C(1)–C(11) oxygen-bridged pregnanes

  摘要：

  1,11-Epoxysteroids may be obtained by an intramolecular remote functionalization using Suarez reagent (diacetoxyiodobenzene/I-2) and irradiation with visible light. We have found that photolysis with visible light may be advantageously replaced by microwave irradiation to prepare 1,11-oxygen bridges resulting in higher yields and shorter reaction times especially in the case of sensitive substrates. Both methodologies were compared on a set of representative 11-alpha-hydroxypregnanes (3, 8, 10 and 11). (C) 2011 Elsevier Inc. All rights reserved.

  摘要：

  这项研究涉及几种新的孕酮，11a-羟基孕酮，11a-叔丁基二甲基硅烷基氧基孕酮和雄激素的衍生物的合成。通过将四种甾族化合物的4-en-3-one部分与2-羟基-1-萘醛缩合，得到一系列的4-（R）-羟基-（2-羟基萘基-1-基）来制备新的衍生物。 ）加合物。这些加合物通过二羟基萘基部分与琥珀酸的环化反应进一步改性，然后将所得的环状琥珀酸酯与乙二胺缩合以形成所有可用羰基上的亚胺衍生物。然后通过用氯乙酰氯对11-和17-亚胺氮进行N-酰化来衍生化这些化合物，然后将所得的氯乙酰胺与2-羟基-1-萘乙醛在Darzens型反应中缩合，从而在侧链中形成相应的环氧乙酰胺。另外，通过NMR光谱数据证实了类固醇衍生物的化学结构。

  A simple route for improving the potency of progesterone as a modulator of P-gp-mediated multidrug resistance was established by esterification or etherification of hydroxylated 5 alpha/beta-pregnane-3,20-dione or 5 beta-cholan-3-one precursors. X-ray crystallography of representative 7 alpha-, 11 alpha-, and 17 alpha-(2'R/S)-O-tetrahydropyranyl ether diastereoisomers revealed different combinations of axial-equatorial configurations of the anomeric oxygen. Substantial stimulation of accumulation and chemosensitization was observed on K562/R7 erythroleukemia cells resistant to doxorubicin, especially using 7 alpha,11 alpha-O-disubstituted derivatives of 5 alpha/beta-pregnane-3,20-dione, among which the 5 beta-H-7 alpha-benzoyloxy-11 alpha-(2'R)-O-tetrahydropyranyl ether 22a revealed promising properties (accumulation index 2.9, IC50 0.5 mu M versus 1.2 and 10.6 mu M for progesterone), slightly overcoming those of verapamil and cyclosporin A. Several 7 alpha,12 alpha-O-disubstituted derivatives of 5 beta-cholan-3-one proved even more active, especially the 7 alpha-O-methoxymethyl-12 alpha-benzoate 56 (accumulation index 3.8, IC50 0.2 mu M). The panel of modulating effects from different O-substitutions at a same position suggests a structural influence of the substituent completing a simple protection against stimulating effects of hydroxyl groups on P-gp-mediated transport.
