Condensation of nitro- and amino-substituted phenylmaleimides with furfuryl alcohol
摘要:
Reaction of nitro- and amino-substituted phenylmaleimides with furfuryl alcohol afforded 4-aza-1-hydroxymethyl-10-oxa-3,5-dioxo-4-N-[nitro(amino)phenyl]tricyclo[5.2.1(1.7).0(2.6)]dec-8-enes. The latter were easily converted into the corresponding phosphites under the action of hexaethyltriamidophosphite.

which carry out a vast array of chemical reactions with remarkable specificity and reaction rates. It is surprising then that there are no documented examples of enzyme-catalyzed pericyclic cycloaddition reactions, yet there are among the most powerful and commonly used reactions in synthetic organic chemistry. The most important of these is the Diels-Alder reaction of a diene with a dienophile, which provides

We have previously reported the discovery and initial SAR optimization of the first series of inhibitors of the human papillomavirus type-11 (HPV11) E1-E2 protein-protein interaction. These inhibitors featured an indandione system spiro-fused onto an all syn substituted tetrahydrofuran ring. In this paper, we report new SAR efforts which have led to the identification of the first low nanomolar inhibitor of the HPV11 E1-E2 protein-protein interaction. In addition, we report a combined NMR and computational chemistry approach which allowed the successful determination of the absolute stereochernistry of the active species originating from the initial racemic lead.
