    摘要:
    The present invention relates to the development of novel compounds of chromeno [4,3-b] quinolone derivatives. It particularly relates to the development of novel compounds of thiochromeno [4,3-b] quinolone derivatives for the treatment of coronary artery diseases, dyslipidemia, and metabolic syndrome. The present invention also relates to the first synthesis of Silicotungstic -catalyzed Aza-Diels-Alder-reactions (ADAR) with s-prenyl derivatives of α-tetralone, 4-chromanone and Thiochroman-4-one and various substituted amines to deliver cycloadducts in good yield and excellent diastereoselectivity under mild reaction conditions. The invention further relates to the method for the treatment of coronary artery diseases, dyslipidemia, and metabolic syndrome by using synthesized compounds of thiochromeno [4,3-b] quinolone derivatives. The present invention provides the use of Silicotungstic acid as Lewis acid for Aza-Diels-Alder-reactions to get a mixture of diastereomers are the first examples. In addition to its efficiency, simplicity, and mild reaction conditions, the catalyst is very cheap and only a small amount (10 mol%) is needed. Intramolecular cyclization was carried out very conveniently as a one-pot reaction starting from the S-prenyl chromene-3-carbaldehyde and arylamines without isolation of the intermediate imines.

    An efficient microwave promoted one-pot synthesis of steroidal and non-steroidal isothiazole derivatives from corresponding β-bromo-α,β-unsaturated aldehydes has been described using a sodium thiocyanate-urea system. The β-bromo-α,β-unsaturated aldehydes derivatives are efficiently synthesized from corresponding cyclic ketones using Vilsmeir formylation reaction. The synthetic protocol is also applied

The high product yields and the ease of the reactions under surprisingly mild conditions are particularly intriguing in view of the complex mechanistic pathway involved in the overall transformation.

    access synthetically challenging cis-2,3-dihydroazepines is reported. The reaction starts with readily available dienals, alkynes, and sulfonyl azides as the substrates and employs copper and rhodium as relay catalysts. Key steps include a copper-catalyzed reaction between an alkyne and a sulfonyl azide to form a triazole intermediate. The subsequent activation of this triazole intermediate by a rhodium

    direct one-pot synthesis of chromeno-annulated imidazo[1,2-a]pyridines is achieved by the reaction of 2-amino-1-(2-ethoxy-2-oxoethyl)pyridinium salts with 2-bromoarylaldehydes using Pd(TFA)2 as a catalyst and Cu(OAc)2 as an oxidant. The overall strategy involves tandem base-mediated amidation and Knoevenagel condensation, followed by palladium-catalyzed Wacker type oxidation and intramolecular C–O coupling
