Rapid access to the core skeleton of the [3 + 2]-type dimeric pyrrole-imidazole alkaloids by triplet ketone-mediated C-H functionalization. Tetrahedron 2018; 74:769-772.

Abstract
The ability of triplet ketones to abstract a hydrogen atom from hydrocarbons is reminiscent of that of the high-spin metal-oxo complexes in C-H oxidation enzymes. In practice, the reactivity of triplet ketones is easier to control and applicable to promoting a wider range of reactions. We demonstrate herein the synthetic utility of triplet ketone-mediated C-addition of methanol to cyclopentenone derivatives with an expedient synthesis of the core skeleton of the [3+2]-type dimeric pyrrole-imidazole alkaloids. Remarkably, this photochemical C-H functionalization reaction is highly regioselective and can tolerate a good range of functional groups.

Abstract
Photoexcited ketones have diradical characteristics and are functionally similar to high-spin metal-oxo species that are frequently used to catalyze C-H oxidation. First discovered by Yang in 1958, photoexcited ketones can abstract a hydrogen atom from hydrocarbons inter- or intramolecularly. Coupling with atom-transfer, group-transfer, or radical addition, the Yang reaction can be used to achieve various types of C-H functionalization. We provide in this article an overview of triplet ketone-mediated or catalyzed C-H functionalization reactions.

Abstract
DNA damage pathways induced by low-energy electrons (LEEs) are believed to involve the formation of 2-deoxyribose radicals. These radicals, formed at the C3' and C5' positions of nucleotides, are the result of cleavage of the C-O phosphodiester bond through transfer of LEEs to the phosphate group of DNA oligomers from the nucleobases. A considerable amount of information has been obtained to illuminate the identity of the unmodified oligonucleotide products formed through this process. There exists, however, a paucity of information as to the nature of the modified lesions formed from degradation of these sugar radicals. To determine the identity of the damage products formed via the 2',3'-dideoxy-C3'-thymidinyl radical (C3'(dephos) sugar radical), phenyl selenide and acyl modified sugar and nucleoside derivatives have been synthesized, and their suitability as photochemical precursors of the radical of interest has been evaluated. Upon photochemical activation of C3'-derivatized nucleosides in the presence of the hydrogen atom donor tributyltin hydride, 2',3'-dideoxythymidine is formed indicating the selective generation of the C3'(dephos) sugar radical. These precursors will make the identification and quantification of products of DNA damage derived from radicals generated by LEEs possible.

Abstract
We synthesized the phosphinate 7 via photoaddition of methanol to the alpha, beta unsaturated deoxyribono lactone as the key step, followed by an Arbusov reaction for the introduction of phosphorous. Precursor 7 serves for the synthesis and incorporation into DNA of a novel chemically stable abasic site analogue that might act as an inhibitor for DNA glycosylases.

Abstract
Starting from D-mannitol, we have prepared several C(2)-symmetric ethanotethered bis(alpha,beta-butenolides) and studied their [2+2] photocycloaddition reaction with ethylene. The protective groups of the central diol unit have a noticeable influence on the facial selectivity of the cycloaddition, the bis(trimethylsilyloxy) derivatives showing the highest diastereoselectivity. A theoretical conformational analysis of the substrates in the ground state is in good agreement with the diastereofacial selectivity experimentally observed. The bis(photocycloadducts) have been converted into the enantiopure cyclobutanes formally derived from the photoreaction of ethylene with gamma-hydroxymethyl-alpha,beta-butenolide, in which only a moderate facial selectivity had been previously found. As an application of these studies, we have developed a highly efficient and stereoselective synthesis of (+)-grandisol.

Abstract
The synthesis of [4,5-bis(hydroxymethyl)-1,3-oxathiolan-2-yl]nucleosides is described. 2,3-Epoxy alcohol 10 was converted in one pot into thioacetate 11. Treatment of 11 under mild alkaline conditions gave thiirane 12 with inversion of configuration at C-2. We also found that thioacetate 11 rearranges into thiirane 14 under mild acidic conditions. This rearrangement reaction was shown by independent synthesis to proceed with net retention of configuration at C-2. We have proposed a tentative mechanism which may explain the results obtained. Opening of thiiranes 12 and 14 followed by deprotection gave (2R,3R)-2-thiothreitol (23) and (2S,3R)-2-thioerythritol (25), respectively. Regioselective silylation of the primary hydroxyl groups of 23 followed by treatment with trimethyl orthoformate gave 2-methoxy-1,3-oxathiolanes 26 and 27. Condensation with silylated bases followed by deprotection and separation of the anomers gave the oxathiolanylnucleosides. Compounds 29-31, 34, and 35 were found to be inactive when tested for inhibition of HIV-1 activity in vitro.

Abstract
The synthesis of 1,3-dioxolan-2-ylnucleosides and related chemistry is described. We have shown that 2-methoxy-1,3-dioxolane (6) reacts with silylated thymine and trimethylsilyl triflate to give the acyclic formate ester 1-[2-(formyloxy)ethyl]thymine (8) rather than 1-(1,3-dioxolan-2-yl)thymine (7). A tentative mechanism which could explain this result is discussed. On the other hand, 2-methoxy-1,3-dioxolane 13c reacts with silylated bases to give [4,5-bis(hydroxymethyl)-1,3-dioxolan-2-yl]nucleosides, thus representing the first examples of this novel class of compounds. The nature of the nucleobase and the hydroxyl protecting groups was found to have great influence on the reaction and on the stability of the nucleosides. Compounds 16 and 18 were found to be inactive when tested for anti HIV-1 activity in vitro.

Abstract
The synthesis of [4,5-bis(hydroxymethyl)-1,3-dithiolan-2-yl]nucleosides is described. (2S,3S)-1,2:3,4-Diepoxybutane (13) was reacted with potassium thiocyanate to give (2R,3R)-1,2:3,4-diepithiobutane (14). Thiiranering opening with acetate followed by deacetylation gave (2R,3R)-2,3-dithiothreitol (19) which was silylated and treated with trimethyl orthoformate to give the 2-methoxy-1,3-dithiolane 20. Condensation of 20 with silylated thymine, uracil, N(4)-benzoylcytosine and 6-chloropurine using a modified Vorbrüggen procedure, followed by deprotection, gave the nucleoside analogues. Compounds 26, 28, and 30 were found to be inactive when tested for anti-HIV activity in vitro.
