Cyclopentanoids and their derivatives are interesting targets in synthetic organic chemistry due to their extensive applications in various branches of chemical sciences like pharmaceuticals, natural and non-natural products. In view of these applications, several synthetic strategies have been developed in the past three to four decades. In this article, we describe our work towards the synthesis of cyclopentanoids and their heteroanalogs involving diverse synthetic strategies during the past two decades. Among these, photo-thermal olefin metathesis, ring-closing metathesis, ring-rearrangement metathesis, cyclopentane annulation, [2+2+2] cycloaddition and Diels–Alder reactions have been used to assemble cyclopentane rings of diverse architecture. 1 Introduction 2 Synthesis of Spiro[4.4]nonane (A1) Derivatives 3 Synthesis of Octahydropentalene (A2) Derivatives 4 Synthesis of Linear Triquinanes (A3) 5 Synthesis Spiro Triquinanes (A4) 6 Synthesis of Angular Triquinane (A5) Systems 7 Synthesis of Hexahydro-2′H-spiro[cyclopentane-1,1′-pentalene] (A6) Ring System 8 Synthesis of Dispiro[4.1.47.25]tridecane (A7) Ring System 9 Synthesis of Hexahydro-1H-3a,7a-propanoindene Ring System 10 Synthesis of Linear Tetraquinanes (A11 and A12) 11 Synthesis of Tetrahydro-1′H,3′H-dispiro[cyclopentane-1,2′-pentalene-5′,1′′-cyclopentane] (A13) Ring System 12 Synthesis of Decahydro-1H,8H-dicyclopenta[a,h]pentalene (A14) Ring System 13 Synthesis of Dodecahydro-1H-dicyclopenta[a,d]pentalene (A15) Ring System 14 Synthesis of Octahydro-1′H-spiro[cyclopentane-1,2′-cyclopenta[c]pentalene] (A16) Ring System 15 Synthesis of Decahydrospiro[cyclopentane-1,7′-cyclopenta-[a]pentalene] (A17) Ring System 16 Synthesis of Compact Tetraquinane (A18) 17 Synthesis of Higher Polyquinanes 18 Conclusions 19 Acronyms

环戊烷类化合物及其杂类似物的模块化方法

环戊烷类化合物及其衍生物是合成有机化学中有趣的目标，因为它们广泛应用于化学科学的各个分支，如药物、天然和非天然产品。鉴于这些应用，在过去的三到四年中已经开发了几种合成策略。在本文中，我们描述了我们在过去二十年中合成环戊烷类化合物及其异类类似物的工作，涉及多种合成策略。其中，光热烯烃复分解、闭环复分解、环重排复分解、环戊烷环化、[2+2+2]环加成和Diels-Alder反应已被用于组装不同结构的环戊烷环。1 引言 2 Spiro 的合成[4．
