Formycin is a naturally occurring C-glycoside (C-nucleoside) that possesses antitumor, antibacterial, antifungal, and antiviral activity. In connection with our ongoing interest in the design and syntheses of C-nucleoside derived antiviral agents this report describes the preparation of carbocyclic formycin and its 7-hydroxy (oxo) analog lacking the C-4' hydroxylmethylene moiety in racemic form (4 and 6, respectively). An antiviral analysis of (+/-)-4 did not disclose any activity.

Reinvestigation of the synthetic and mechanistic aspects of Mn(III) acetate mediated oxidation of enones
Demir, Ayhan Sıtkı; Reis, O; Igdir, AC (Elsevier BV, 2004-04-05)
Mn(OAc)(3) mediated alpha'-acetoxylation of alpha,beta-unsaturated enones is reinvestigated from a synthetic and mechanistic point of view and an improved procedure based on the use of acetic acid as a co-solvent is presented. Excellent results were obtained for a variety of structurally diverse and synthetically important enones under the optimized conditions.
Chemosensing in deep red: A squaraine-based fluorescent chemosensor for pH.
Isgor, YG; Akkaya, EU (Elsevier BV, 1997-10-20)
We have synthesized and spectrally characterized a squaraine-based fluorescent chemosensor for pH. This chemosensor unlike many others, works in 100 % aqueous solutions, signalling the pH change from 10 to 7 by a 11-fold increase in the emission intensity at 651 nm, when excited at the isosbestic point (614 nm). The average pK(a) for the ionizable groups is found to be 8.8. The chemosensor with its molar extinction coefficient > 200,000 and the quantum yield of 0.2, yield an impressive intrinsic brightness ...
Enzyme catalyzed hydroxymethylation of aromatic aldehydes with formaldehyde. Synthesis of hydroxyacetophenones and (S)-benzoins
Demir, Ayhan Sıtkı; Ayhan, P; Igdir, AC; Duygu, AN (Elsevier BV, 2004-07-26)
Benzaldehyde lyase from the Pseudomonas Fluorescens catalyzed reaction of aromatic aldehydes with formaldehyde providing 2-hydroxy-1-arylethan-1-one in high yields via an acyloin linkage. Kinetic resolution of rac-benzoins with formaldehyde providing (S)-benzoins and 2-hydroxy-1-arylethan-1-one via C-C bond cleavage and a bond formation reaction.
Benzaldehyde lyase catalyzed synthesis of novel acyloins
Şimşek, İlke; Demir, Ayhan Sıtkı; Department of Chemistry (2009)
α-Hydroxy phosphonates are versatile building blocks for the synthesis of many biologically active compounds that display antiviral, antibacterial, anticancer, pesticide activities beside their enzyme inhibitory activities such as they are the inhibitors of rennin or human immunodeficiency virus (HIV) protease and polymerase. Benzaldehyde lyase is able to catalyze not only C-C bond formation reactions but also C-C bond breaking reactions with high enantioselectivity that brings about the development of new ...
Zinc perchlorate catalyzed one-pot amination-annulation of alpha-cyanomethyl-beta-ketoesters in water. Regioselective synthesis of 2-aminopyrrole-4-carboxylates
Demir, Ayhan Sıtkı; Emrullahoglu, M (Elsevier BV, 2006-02-13)
In this paper, we report the efficient and regioselective synthesis of 2-aminopyrrole-4-carboxylates as derivatives of conformationally restricted analogues of gamma-amino butyrates (GABA) via a zinc perchlorate catalyzed amination-annulation of alpha-cyanomethyl-beta-ketoesters under mild reaction conditions in water.
