Canestrari, Daniele ORCID: 0000-0002-3245-6630
A conceptionally novel nucleophilic substitution approach to synthetically important alkyl bromides is presented. Using molecular bromine (Br2), readily available secondary benzyl and tertiary alkyl phenyl sulphides are converted into the correspondi

A simple and practical protocol for the construction of synthetically important quaternary α-benzyl- and α-allyl-α-methylamino cyclobutanones in good to high yield, via a sequential one-pot methylation/sigmatropic rearrangement, has been accomplis

An asymmetric synthesis of α-aryl amino-β-nitro cyclohexanes has been achieved by means of a tandem aza-Michael addition-protonation reaction starting from 1-nitro cyclohexene and anilines. The transformation is proposed to proceed via a transient

A two-step protocol is presented for the preparation of 5-(pyridin-2-ylamino)dihydrofuran-2(3H)-ones from 2-hydroxycyclobutanone and some 2-aminopyridines via a catalyst-free synthesis of 2,2-bis(pyridin-2-ylamino)cyclobutanols followed by Dess–Mar
