Paragraph 00549-00550, (2016/07/05)
The present invention relates to novel geminal substituted quinuclidine amide compounds, and pharmaceutical compositions of the same, that are suitable as agonists or partial agonists of α7- nAChR, and methods of preparing these compounds and compositions, and the use of these compounds and compositions in methods of maintaining, treating and/or improving cognitive function. In particular, methods of administering the compound or composition to a patient in need thereof, for example a patient with a cognitive deficiency and/or a desire to enhance cognitive function, that may derive a benefit therefrom.

(Chemical Equation Presented) A key directed remote metalation (DreM)-carbamoyl migration strategy was applied in an efficient synthesis of the naturally occurring 6H-naphtho[1,2-b]benzopyran-6-one defucogilvocarcin V (1a, Scheme 11). The required biarylcarbamate 33d was best prepared by a high yielding Suzuki coupling reaction of 31a with the differentially protected trioxygenated naphthalene coupling partner 32d which was synthesized using a selective acylation of a juglone derivative. In the late stages of the synthesis, the triflate 39 served as the common intermediate to install the required C-8 vinyl group of 1a (Stille coupling) as well as the required substituents for the preparation of defucogilvocarcins M (1b) and E (1c). A variety of protecting group strategies were investigated and provided insight into which groups are preferred for the DreM-carbamoyl migration process. The strategic lessons learned from this total synthesis were applied in the successful total synthesis of the structurally similar natural product arnottin I (2).
