The stereoselective addition of the 2-hydroxyl group of glucose to the mercurated vinyl group of 2-alkenyl glycosides followed by hydride reduction and removal of the saccharide fragment was used to prepare enantiomerically pure 1,2-dihydroxy alkanes. Diols of (R) or (S) configuration can be synthesized from (alpha)-glycosides or the (beta) form respectively. Demercuration with chloride ion led to the insertion of a halo group adjacent to the new chiral center thus allowing for the possibility of further functionalization.

A simple and highly active catalytic process for ring-opening alternating copolymerization (ROAC) of cyclic anhydrides and epoxides still remains a key challenge. Herein, we have described an effective group of versatile and low-toxic zinc dicarbyl/amine Lewis pairs for the ROAC. The facile route showed a high catalytic activity (TOF ? 210 h-1 at 110 C) and perfectly alternating selectivity (>99%). An unexpected highly regioselective ring-opening of asymmetric epoxides (PO, ECH and SO) was also achieved by the combination of zinc alkyls (or aryls) and amines. Of note, deprotonation side reaction of alpha-H of anhydrides with organic bases was uncovered, and subsequently was inhibited by using nonpolar solvents and Lewis acid/base pairs. Thus, an array of polyesters was synthesized by the coupling of various anhydrides (PA, CHA, SA and NA) and epoxides (CHO, PO, ECH and SO) using the same Lewis pairs. Furthermore, variable temperature 1H NMR spectral and MALDI TOF MS analyses were performed to understand the possible mechanism and microstructure. The experimental results indicated that zwitterionic alkoxide and carboxylate intermediates alternately formed to enhance the ester repeat units in chain initiation and propagation. This work provides a simple and green catalytic strategy to prepare diversified polyesters from the ROAC process of cyclic anhydrides and epoxides with considerable catalytic activity and alternating selectivity.

One aspect of this disclosure relates generally to lipid compounds that exert diverse effects in the endocannabinoid system, such as regulating CB1 and CB2 receptor or moderating other bio-macromolecules within the endocannabinoid system. Some of the compounds showed improved receptor binding affinity, and/or improved receptor subtype selectivity, and improved bio-stability. Some of the compounds exhibit activities to regulate the enzymes that moderate the bio-disposal of endogenous cannabinoids, such as the fatty acid amide hydrolase (FAAH). Some of the compounds exhibit activities to inhibit the anandamide transporter. Other aspects of the invention are pharmaceutical preparations employing these ligands and methods of administering therapeutically effective amounts of the preparations to provide a physiological effect.

A number of methyl derivatives of 9-[2-(phosphonomethoxy)ethyl]guanine (PMEG, 1) have been synthesized and tested in vitro for anti-herpes and anti- human immunodeficiency virus (HIV) activity. Among these analogues, (R)-2′- methyl-PMEG [(R)-3] and 2′,2′-dimethyl-PMEG (7) demonstrated potent anti-HIV activity in the XTT-assay with EC50 values of 1.0 and 2.6 muM, respectively. The corresponding (S)-2′-methyl-PMEG [(S)-3] was found to be less potent against HIV. In addition, the (R) and (S) enantiomers of 9-[3- hydroxy-2-(phosphonomethoxy)propyl]guanine (HPMPG, 8) were prepared for comparison of biological activity, and shown to be active and equipotent against herpesviruses, but inactive against HIV.
