Journal ArticleDOI
Synthesis of enantiomerically pure all cis-2,3,6-trisubstituted piperidine: a silicon mediated total synthesis of (+)-carpamic acid
Rekha Singh,Sunil K. Ghosh +1 more
TL;DR: In this article, a stereoselective total synthesis of (+)-carpamic acid was achieved from the σ-symmetric 3-[dimethyl(phenyl)silyl]glutaric anhydride featuring its asymmetric desymmetrisation using oxazolidinone.
Journal ArticleDOI
A Novel Approach Towards Dibenzylbutyrolactone Lignans Involving Heck and Radical Reactions: Application to ()-Matairesinol Synthesis
TL;DR: In this article, a highly regio-and stereoselective Heck reaction of iodoarenes with vinylated malonates, generated in situ by fluoride-induced protiodesilylation of alkenylsilanols/disiloxanes to give functionalized styrenes and 1,4-diaryl-1-butenes has been developed.
Journal ArticleDOI
The unprecedented reaction of dimethylsulfonium methylide with Michael acceptors: synthesis of 1-substituted vinyl silanes and styrenes
TL;DR: Rather than the usual cyclopropanation, conditions for an unprecedented elimination reaction from the adduct of dimethylsulfonium methylide and various Michael acceptors have been established leading to functionalized 1-substituted alkenes.
Journal ArticleDOI
A novel reaction of dimethylsulfonium methylide with Michael acceptors: application to the synthesis of difficultly accessible vinyl silanes and styrenes
TL;DR: In this paper, conditions for a novel elimination reaction from the adduct of 2-silylalkylidene/arylidene malonate/cyanoacetate/phosphonoacetate leading to geminally substituted vinyl silanes or styrenes, respectively, have been established.
Journal ArticleDOI
Catalytic nucleophilic fluorination by an imidazolium ionic liquid possessing trialkylphosphine oxide functionality
TL;DR: In this article, the synthesis of a new alkylmethylimidazolium ionic liquid with dihexylphosphine oxide moiety at the terminal position has been achieved in four steps.
