Enantiocontrolled Preparation of ϒ-Substituted Cyclohexenones: Synthesis and Kinase Activity Assays of Cyclopropyl-Fused Cyclohexane Nucleosides. Int J Mol Sci 2022; 23:ijms23179704. [PMID: 36077100 PMCID: PMC9456008 DOI: 10.3390/ijms23179704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/22/2022] [Accepted: 08/23/2022] [Indexed: 11/25/2022] Open
Abstract
The enantioselective preparation of the two isomers of 4-hydroxy-2-cyclohexanone derivatives 1a,b was achieved, starting from a common cyclohexenone, through asymmetric transfer hydrogenation (ATH) reactions using bifunctional ruthenium catalysts. From these versatile intermediates, a stereoselective route to a cytosine analogue built on a bicyclo [4.1.0]heptane scaffold is described. Nucleoside kinase activity assays with this cyclopropyl-fused cyclohexane nucleoside, together with other related nucleosides (2a–e), were performed, showing that thymine- and guanine- containing compounds have affinity for herpes simplex virus Type 1 (HSV-1) thymidine kinase (TK) but not for human cytosolic TK-1, thus pointing to their selectivity for herpetic TKs but not cellular TKs.

Abstract
The Robinson annulation is a reaction that has been useful for numerous syntheses since its discovery in 1935, especially in the field of steroid synthesis. The products are usually obtained after three consecutive steps: the formation of an enolate (or derivative), a conjugate addition, and an aldol reaction. Over the years, several methodological improvements have been made for each individual step or alternative routes have been devised to access the Robinson annulation products. The first part of this Review outlines the most relevant developments towards the formation of monocarbonyl-derived Robinson annulation products (MRA products, MRAPs) and activated monocarbonyl-derived Robinson annulation products (AMRA products, AMRAPs). The following sections are then devoted to the diastereoselective and enantioselective synthesis of these products, while the last section describes the enantiomeric resolution of racemic mixtures.

Abstract
HIV-1 Tat is one of six regulatory proteins that are required for viral replication and is an attractive target for the development of new anti-HIV agents. Screening of microbial extracts using a whole cell Tat-dependent transactivation assay, which guided the separation of the active broths, led to the identification of five structurally diverse classes (M(R) range 232-1126) of natural products. These include i) three sesquiterpenoids, namely, sporogen-AO1, petasol, and 6-dehydropetasol, ii) two resorcylic 14-membered lactones, namely monorden and monocillin IV, iii) a ten-membered lactone, iv) a quinoline and quinoxiline bicyclic octadepsipeptides, namely echinomycin and UK-63598, and v) a cyclic heptapeptide, ternatin. These compounds displayed varying degrees of potencies with IC50 values ranging from 0.0002 to 100 microM. The most active compound was the quinoxiline bicyclic octadepsipeptides, UK-63598, which inhibited Tat-dependent transactivation with an IC50 value of 0.2 nM and exhibited a 100-fold therapeutic window with respect to toxicity. In a single-cycle antiviral assay, UK-6358 inhibited viral replication with an IC50 value of 0.5 nM; however, it appeared to be equally toxic at that concentration. Monocillin IV was significantly less active (Tat transactivation inhibitory IC50 of 5 microM) but was not toxic at 100 microM in an equivalent cytotoxicity assay. The compound exhibited antiviral activity with an IC50 value of 6.2 microM in the single-cycle antiviral assay and a sixfold therapeutic window. Details of the isolation, fermentation, and biological activities of these structurally diverse natural products are described.

Abstract
Alkylation of 1,4-cyclohexanedione monoethylene acetal SAMP-hydrazone with various electrophiles (10 examples given) and subsequent cleavage of the hydrazones with saturated oxalic acid furnished highly enantiomerically enriched alpha-alkylated mono-protected 1,4-cyclohexanedione derivatives in high yields and enantiomeric excesses of ee = 28, 80->/=99%. Reduction of the ketones gave the corresponding alcohols in good yields with high enantiomeric excesses (ee = 80->/=98%) and cis/trans-ratios of usually 85:15.
