Thompson L, Kinsey A, Shahla Z, Scheerer J
J Org Chem . 2024 Nov; 89(23):17635-17642. PMID: 39532705
This study describes a general method for the preparation of 1,4-oxazin-2-one intermediates from acetylene dicarboxylate and β-amino alcohol precursors. Oxazinones prepared in this manner were employed in a tandem cycloaddition/cycloreversion...

Lehman V, Ma Y, Scheerer J
J Org Chem . 2024 Jul; 89(15):11078-11082. PMID: 39014934
This study describes the synthesis of the 4-azafluorenone core in a single operation using readily available starting materials. Condensation of an amidrazone with ninhydrin intercepts an intermediate 1,2,4-triazine derivative, which...

Scheerer J, Leeth E, Sprow J
Synthesis (Stuttg) . 2023 Sep; 55(15):2319-2324. PMID: 37691879
A new method to prepare 1,4-oxazinone intermediates was developed based on aza-conjugate addition of β-amino alcohols to electron-deficient alkyne precursors. A tandem intramolecular cycloaddition/cycloreversion reaction sequence was evaluated, leading to...

Pudner G, Camp I, Scheerer J
J Org Chem . 2022 May; 87(12):8213-8222. PMID: 35613467
This study investigates a synthetic sequence for the preparation of 1,2-diketone products. The sequence avoids oxidative conditions and instead employs reliable transformations including the Horner-Wadsworth-Emmons and addition of Grignard reagents...
5.
Carrillo Vallejo N, Scheerer J
J Org Chem . 2021 Apr; 86(8):5863-5869. PMID: 33797249
This study reveals a new method for the preparation of 1,4-oxazinone derivatives by Staudinger reductive cyclization of functionalized vinyl azide precursors. The resulting oxazinone derivatives prepared in this manner were...
6.
Angello N, Wiley R, Abelt C, Scheerer J
Molecules . 2020 Jul; 25(15). PMID: 32722081
A new extension for the 'one pot' construction of diverse 1-azafluorene derivatives featuring a Diels-Alder/retro-Diels-Alder cycloaddition is reported. Conditions were also determined for oxidation to the derived azafluorenones. The spectrophotometric...

Maisto S, Leersnyder A, Pudner G, Scheerer J
J Org Chem . 2020 Jul; 85(14):9264-9271. PMID: 32602717
This study reveals an alternative sequence for the synthesis of compounds that contain the pyrrolodiketopiperazine structural motif. Starting with a diketopiperazine precursor, a mild aldol condensation precedes pyrrole annulation and...

Smith Z, Wang X, Scheerer J, Martens J, Berden G, Oomens J, et al.
J Am Soc Mass Spectrom . 2019 Jun; 30(9):1565-1577. PMID: 31183839
Infrared multiple photon dissociation action spectroscopy was performed on the AlaOrn b and AlaAlaOrn b fragment ions from ornithine-containing tetrapeptides. Infrared spectra were obtained in the fingerprint region (1000-2000 cm)...
9.
Angello N, Wiley R, Elmore T, Perry R, Scheerer J
Org Lett . 2018 Aug; 20(17):5203-5207. PMID: 30095269
A new domino reaction sequence for the construction of 2-pyridone structures is reported. The reaction sequence begins with diacetyldiketopiperazine and proceeds via aldol condensation, alkene isomerization, and intramolecular Diels-Alder cycloaddition....

Williamson J, Smith E, Scheerer J
Synlett . 2018 Feb; 28(10):1170-1172. PMID: 29398786
A domino reaction sequence has been evaluated that begins with union of novel dihydrooxazinone precursors with 2-alkynyl-substituted benzaldehyde components through aldol condensation. Ensuing operations, including alkene isomerization, Diels-Alder, and retrograde...
