Abstract
![]()
Many
polycyclic marine
alkaloids are thought to derive from partly
reduced macrocyclic alkylpyridine derivatives via a transannular Diels–Alder
reaction that forms their common etheno-bridged diaza-decaline core
(“Baldwin–Whitehead hypothesis”). Rather than
trying to emulate this biosynthesis pathway, a route to these natural
products following purely chemical logic was pursued. Specifically,
a Michael/Michael addition cascade provided rapid access to this conspicuous
tricyclic scaffold and allowed different handles to be introduced
at the bridgehead quarternary center. This flexibility opened opportunities
for the formation of the enveloping medium-sized and macrocyclic rings.
Ring closing alkyne metathesis (RCAM) proved most reliable and became
a recurrent theme en route to keramaphidin B, ingenamine, xestocyclamine
A, and nominal njaoamine I (the structure of which had to be corrected
in the aftermath of the synthesis). Best results were obtained with
molybdenum alkylidyne catalysts endowed with (tripodal) silanolate
ligands, which proved fully operative in the presence of tertiary
amines, quinoline, and other Lewis basic sites. RCAM was successfully
interlinked with macrolactamization, an intricate hydroboration/protonation/alkyl-Suzuki
coupling sequence, or ring closing olefin metathesis (RCM) for the
closure of the second lateral ring; the use of RCM for the formation
of an 11-membered cycle is particularly noteworthy. Equally rare are
RCM reactions that leave a pre-existing triple bond untouched, as
the standard ruthenium catalysts are usually indiscriminative vis-à-vis
the different π-bonds. Of arguably highest significance, however,
is the use of two consecutive or even concurrent RCAM reactions en
route to nominal njaoamine I as the arguably most complex of the chosen
targets.

Abstract
Fatty acid oxidation (FAO) produces most of the ATP used to sustain the cardiac contractile work, although glycolysis is a secondary source of ATP under normal physiological conditions. FAO impairment has been reported in the advanced stages of heart failure (HF) and is strongly linked to disease progression and severity. Thus, from a clinical perspective, FAO dysregulation provides prognostic value for HF progression, the assessment of which could be used to improve patient monitoring and the effectiveness of therapy. Positron emission tomography (PET) imaging represents a powerful tool for the assessment and quantification of metabolic pathways in vivo. Several FAO PET tracers have been reported in the literature, but none of them is in routine clinical use yet. Metabolically trapped tracers are particularly interesting because they undergo FAO to generate a radioactive metabolite that is subsequently trapped in the mitochondria, thus providing a quantitative means of measuring FAO in vivo. Herein, we describe the design, synthesis, tritium labelling and radiofluorination of 4,4,16-trifluoro-palmitate (1) as a novel potential metabolically trapped FAO tracer. Preliminary PET-CT studies on [18 F]1 in rats showed rapid blood clearance, good metabolic stability - confirmed by using [3 H]1 in vitro - and resistance towards defluorination. However, cardiac uptake in rats was modest (0.24±0.04 % ID/g), and kinetic analysis showed reversible uptake, thus indicating that [18 F]1 is not irreversibly trapped.

Abstract
The Pauson-Khand reaction is a powerful tool for the synthesis of cyclopentenones through the efficient [2 + 2 + 1] cycloaddition of dicobalt alkyne complexes with alkenes. While intermolecular and intramolecular variants are widely known, transannular versions of this reaction are unknown and the basis of this study. Macrocyclic enyne and dienyne complexes were readily synthesized by palladium(II)-catalyzed oxidative macrocyclizations of bis(vinyl boronate esters) or ring-closing metathesis reactions followed by complexation with dicobalt octacarbonyl. Several reaction modalities of these macrocyclic complexes were uncovered. In addition to the first successful transannular Pauson-Khand reactions, other intermolecular and transannular cycloaddition reactions included intermolecular Pauson-Khand reactions, transannular [4 + 2] cycloaddition reactions, intermolecular [2 + 2 + 2] cycloaddition reactions, and intermolecular [2 + 2 + 1 + 1] cycloaddition reactions. The structural and reaction requirements for each process are presented.
