5-Exo-dig radical cyclization of enediynes: the first synthesis of tin-substituted benzofulvenes.
[reaction: see text] Bu(3)Sn-mediated 5-exo-dig radical cyclization of diaryl enediynes provides a mild and efficient approach to tin-substituted fulvenes. Further synthetic opportunities opened by this process and general factors responsible for the observed regio- and stereoselectivity are outlined.
متن کاملSynthesis of functionalized ellipticinium and ellipticine derivatives via electrophilic cyclization.
An efficient methodology for the synthesis of highly functionalized ellipticinium and ellipticine derivatives starting from the corresponding 2-bromocarbazoles via an AgOTf or CuI catalyzed electrophilic cyclization of 2-alkynyl-3-carbazolylaldimines is reported.
متن کاملSynthesis of cycloheptanoid natural products via tandem 5-exo cyclization/Claisen rearrangement process.
This article describes the development of microwave-assisted oxyanionic 5-exo-dig cyclization-Claisen rearrangement sequence as a convenient "one-pot" route to a variety of seven-membered carbocyclic ring systems. This process was used as the key transformation for the construction of several natural products, including frondosins A, B, and C.
متن کاملSynthesis of substituted dihydrobenzofurans via tandem S(N)Ar/5-exo-trig cyclization.
A tandem SNAr/5-exo-trig cyclization reaction is reported that converts N-alkyl- and -arylimines derived from o-fluorobenzaldehydes into 3-amino-2,3-dihydro-2,2-diarylbenzofurans in moderate to good yields. Diarylmethoxide coupling partners serve the dual role of nucleophile in the SNAr step and catalytic base in the cyclization step. With a subset of the substrates, a further base-induced elim...
متن کاملThe 5-exo-dig Cyclization of Bmdms Propargylic Ethers: an Efficient Trigger for Radical Cascades
This article reviews our contribution in the field of radical synthetic chemistry, focusing on cascades relying on the use of propargylic BMDMS ethers and asymmetric synthesis using enantiopure vinylsulfoxides. THE 5-EXO-DIG CYCLIZATION OF BMDMS PROPARGYLIC ETHERS: AN EFFICIENT TRIGGER FOR RADICAL CASCADES The vinyl radical, a precious tool The vinyl radical of type 3 resulting from the highly ...
