Abstract:
Exchange dioxolanation of 2-methyl-2-(prop-2′-enyl)cyclopentane-1,3-done (1b) gave 3,3- ethylenedioxy-2-methyl-2-(prop-2′-enyl) cyclopentan-1-one (2) which, upon reduction and esterification , afforded the epimeric 3,3-ethylenedioxy-2-methyl-2-(prop-2′-enyl) cyclopent-1-yl benzoates (6d). Oxidative cleavage of the terminal double bond in (6d),followed by sodium borohydride reduction yielded 3,3-ethylenedioxy-2-(2'-hydroxyethyl)-2-methylcyclopent-1-yl benzoate (4b) which underwent acid- catalysed rearrangement to 6a-(2′-hydroxyethoxy)-3a- methylhexahydrocyclopenta [b]furan-4-yl benzoate (8b).

Abstract:
The reaction between N-tosyl-N-[6-(2-cyclopenten-1-yl)phenyl]glycine (syn/anti atropisomeric mixture) and molecular iodine is studied. Along with the expected 8-exo-cyclization product possessing a 3-iodo-2,3,3a,6,7,11b-hexahydrobenzo[e]cyclopenta[g][1,4]oxazocine core, the unexpected 1,11b-dehydrogenated/1-iodinated analogue with a 1,3-diiodo-3,3a,6,7-tetrahydrobenzo[e]cyclopenta[g][1,4]oxazocine structure is observed for the first time in a conventional halolactonization reaction.

Abstract:
AbstractCyclopentanoids 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-rear

All the cyclohexane rings adopt chair conformations and the cyclopentane ring adopts a twisted envelope conformation, with the C atom bearing the tosylmethyl substituent forming the flap. In the crystal, molecules form a three-dimensional network through multiple weak C—H...O hydrogen bonds.

Abstract:
Electric current is known to flow through the π-bonds in oligothiophenes. In order to use them as molecular wires it is important to use a technique where the potential gradients can be generated and maintained in supramolecular networks. A solution to this problem can be the use of metal complexes as junction points within such a network.  In this project pathways to synthesize 2-thia-7,8-diaza-cyclopenta[l]phenanthrene (1) and 1-thia-7,8-diaza-cyclopenta[l]phenanthrene (2) for use in molecular electronic devices have been investigated. 4-(5-Bromo-thiophen-2-yl)2,2’-bipyridine (3) was prepare
