摘要

本論文主要分為三個章節。在第一章節，主要是分為四個部分，其中A部分是回顧有關於在水的條件下所進行反應之相關文獻報導，在B部分和C部分是描述硝基苯乙烯與環狀1,3-雙羰基化合物在水的條件下進行反應以及內環磺胺類衍生物之合成，C部分則是介紹藉由矽膠在微波條件下進行一鍋化兩步合成以羥基亞胺基二氫苯呋喃類之衍生物。

在第二章節中，介紹藉由過渡金屬催化合成內環磺胺類衍生物以及其多方面的合成應用。在第二章節裡，主要是分為四個部分，其中A部分是回顧有關於合成內環磺胺類衍生物之相關文獻報導，這部分同時也簡要概述有關於三氮唑以往的合成方式和文獻探討。B部分是描述有效率且以一鍋化的方式，藉由銅催化[3+2]環加成反應來合成triazolothiadiazepine-1,1-dioxide之衍生物，以及利用上述的方法合成分別以吲哚啉和噻吩結合內環磺胺類之衍生物。而C部分是介紹一種新穎的合成策略，其藉由溴環化反應來合成出含有雙溴的呋喃結合內環磺胺類之衍生物，而此合成方法也可以應用於合成tetrahydrofuroisoquinolin-5(9bH)-one之衍生物。D部分是探討一種有效率且具有位向選擇性的合成方法，其藉由碘環化反應來合成出4-iodo-2,3-disubstituted-2H-thieno[3,2-e][1,2]thiazine-1,1-dioxide之衍生物。將所得到的產物4-iodo-2,3-disubstituted-2H-thieno [3,2-e] [1,2] thiazine-1,1-dioxide與一系列的硼酸（Suzuki偶聯反應）和活潑烯烴（Heck 偶聯反應）進行偶聯反應。經Sonogashira偶聯反應後的產物可以有效率地合成為疊氮化合物的前驅物，其可以多方面的合成應用於合成出三氮唑結合噻吩和內環磺胺類之衍生物。在第三章節中，主要是收錄整本論文中所有標記的化合物之1H和13C光譜圖以及X光晶體的數據。

The content of this dissertation is divided into three parts. The part I is subdivided into four sections. Section A, illustrate the overview on ‘on water’ reactions and
related literature review. Section B and C describes the ‘on water’ reactions of nitrosytrenes with cyclic 1,3-dicarbonyl compounds and also the synthesis of
hydroxyiminodihydrofuroquinolinone derivatives. Section D deals with one-pot, twostep synthesis of hydroxyiminodihydrobenzofurans mediated by silica gel under
microwave activation condition.
Part II deals with the synthesis of fused sultam derivatives by using transition metal catalysed reactions and their appliation towards diversity oriented synthesis. Part II is subdivided into four sections. Section A, deals with overview, classification and synthetic approaches of fused Sultam derivatives. This section also describe the brief overview on triazole synthesis and literature survey. Section B, describes an efficient and one-pot synthesis of triazolothiadiazepine-1,1-dioxide derivatives via copper
catalyzed tandem [3+2] cycloaddition/N-Arylation and utilization of this method to synthesize indoline and thiophene fused sultam. Section C deals with the novel
synthesis of angular diborminated furosultam derivaitves via bromocyclization strategy. This method is also applicable for the synthesis of tetrahydrofuroisoquinolin-
5(9bH)-one. Section D, demonstrate an efficient and regioselective synthesis of 4-iodo-2,3-disubstituted-2H-thieno[3,2-e][1,2]thiazine-1,1-dioxide derivatives via
iodocyclization approach. The resulting 4-iodo-2,3-disubstituted-2H-thieno[3,2-e][1,2]thiazine-1,1-dioxide utilized to couple with a array of boronic acids (Suzuki
coupling) and activated alkenes (Heck coupling). The Sonogashira coupled product was efficiently transformed to azido precursor, which was exploited for the diversity
oriented synthesis of triazole linked thieno-sultam derivatives.
Part III comprises of 1H and 13C NMR spectral copies and X-Ray crystallograpic data of all the compounds incorporated in this thesis.
