Abstract:
The synthesis of C-aryl/alkyl 2C-branched sugar-fused isochromans by using a carbohydrate-derived starting material is described. Our approach makes use of sequential Prins and Friedel–Crafts cyclizations in which a Perlin aldehyde derived homoallylic alcohol is converted into the target molecule. This strategy works well with many aldehydes and gives good yields with excellent selectivity.

Aldehydes have been condensed with malonic acid using a mixture of pyridine (I mol.) and piperidine (traces) by Haworth, Perkin. and Rankin (J. Chem. Soc.. 1924, 125, 1693) and by Dutt (J. Indian&nbsp;Chem. Soc<em>., </em>1925, 1, 297) and a few other bases each in molecular proportions (Dalal and Dutt, ibid.<em>, </em>1932. 9, 309). The pyridine-piperidine method, originally given by Haworth, Perkin and Rankin (loc. cit.)<em> </em>and modified by Robinson and Shinoda (J. Chem. Soc., 1924, 1693) has been applied by Chakravarti, Haworth and Perkin, who using <em>m- </em>methoxybenzaldellyde and

Abstract:
Aim and Objective: The benzimidazole derivatives have been obtained via weightreducing aid (L-Carnitine) as a cheap catalyst. A wide range of aromatic aldehydes easily undergo condensations with substituted o-phenylendiamine under mild condition to afford the target molecular in excellent yields. Materials and Methods: Melting points were measured on an Electrothemal X6 microscopy digital melting point apparatus. 1H NMR and 13C NMR spectra were recorded in DMSO-d6 on a Bruker AVANCE 400 (400 MHz) instrument with the TMS at d 0.00 ppm as an internal standard. C, H and N analysis were performed

Abstract:
This chapter assesses some of the ways in which photochemistry has an impact on our lives. Natural photochemical phenomena have contributed to the evolution of life as we know it, and permit its continued existence on Earth. Indeed, photochemical reactions have performed a determining role in the evolution of the Earth's atmosphere. The forms and ecology of life that have been viable at any time in the past were directly dependent on the constitution of the atmosphere during that period. Photosynthesis is perhaps the most important of the many interesting photochemical processes known in biolo
