Synthesis of 3-methoxybenzyl alcohol

Many students (including the author) take a one-semester fundamental chemistry lecture and laboratory course (CHEM 102) that surveys the basics of organic chemistry and biochemistry (Van Lanen, 2000). It is organized around topics of organic chemistry, but with some biological perspective (Miner, 1948; Isom, 2006). This course is often required for students in health-oriented programs, especially the nursing program (at the University of South Carolina, Chemistry 102 is required in the nursing curriculum, as shown ), and it may also serve as a laboratory science for students in other fields of study (Price, 1976; Mamantov and Wyatt, 1978). Emphasis for this course is often placed on selected principles relevant to the understanding of human biological functions and related medical aspects. However, this course is often seen by students as a difficult and professionally irrelevant barrier in pursuing a career in medicine or nursing. Moreover, even though knowing detailed chemical properties of organic molecules is not a main objective for this course, students are required to comprehend some basic organic reactions, especially those closely related to biochemical processes of the human body. Some typical examples are the oxidation of an alcohol, the formation of a disulfide bond, carboxylic acid and amine dissociation, esterification, and amide formation. However, learning organic reactions for non-science major students has often been unpleasant (Rowe, 1983; Burgess and Bino, 1988).

Stereoselective Synthesis of 1,3-Amino Alcohols by the …

This paper delineates a clear way to learn the fundamentals of organic chemistry and biochemistry for students ranging from those preparing for careers in the health field to non-science majors. It looks in depth at the reactions relevant to the biochemical processes of the human body, such as the reactions involving alcohols, carboxylic acids, esters, amines, amides, and disulfides. The objective is to present the subject matter in such a way that peer students can clearly relate it to topics relevant to their particular fields of study. This can be done using mnemonic assists such as acronyms, or by using real-life examples of how these chemical reactions occur in the human body or in the processing of various pharmaceuticals. These methods provide students with concrete and practical examples of how chemistry is used in the medical field, enabling them to have a firmer grasp of the concepts necessary to succeed in the course.

N2 - A library of 200 2-alkyl-3-alkyloxy-2H-indazole-6-carboxamides was synthesized using parallel solution-phase methods. The indazole cyclization reaction was optimized for library production with the best yields resulting from controlled alcohol/water solvent ratios. The key step, a heterocyclization reaction, proceeds by N,N-bond formation and delivers the 2H-indazole scaffold. Automated preparative HPLC was utilized to provide pure compounds on a 10+ mg scale.

There are many different types of alcohol. The proper name for alcohol is alkanol. The main functional group of alcohols (alkanols) is the hydroxyl or -OH group.

So, wax. According to wikipedia, a wax is just a plastic/malleable compound that melts slightly above room temperature to give a non viscous liquid. As this definition doesn't stipulate any chemical properties, there's a pretty large number of compounds which fall into this bracket, and so waxes from different sources can have very different chemical compositions. Wax from natural sources such as insects and animals tends to be composed of the esters of various fatty acids with long chain alcohols, whereas synthetic waxes tend to be simple mixtures of various long chain hydrocarbons. Earwax is different again.[1] Regardless of its provenance, wax can be a pretty useful substance, with myriad uses around the lab. Here are the first five I can think of; no doubt there are others!

AB - Treatment of 2,3.5-tri-O-benzyl-ß-D-ribofuranosylethyne (2) with a large excess of paraformaldehyde and potassium hydroxide in ethanol gave 3-(2,3,5-tri-O-benzyl-ß-D-ribofuranosyl)prop-2-yn-1-ol (5) in 70% yield. Oxidation of (5) with chromic oxide (Jones reagent) afforded the carboxylic acid (4) (75%). esterification of which with diazomethane gave the known ester (7). Similar reactions and correlations have been carried out in the a-séries. Reaction of the Grignard reagent (14) of 3-(tetrahydropyran-2-yloxy)propyne with 2,3,5-tri-O-benzyl-D-ribo-furanose (19) followed by ring closure and removal of the tetrahydropyranyl ether group gave the alcohol (5) in 52% overall yield. Careful oxidation of (5) gave the corresponding aldehyde (3) which yielded the known pyrazole (1) (72%) on treatment with hydrazine. When 1.2-dideoxy-4.5:7,8-di-O-isopropylidene-D-manno- oct-1-yn-3-ulofuranose (22) was treated with hydrazine. 3(5)-(1.2:4,5-di-O- isopropylidene-D-manno-pentahydroxypentyl)pyrazole (23) was isolated in 93% yield.

In a similar way, the –OH groups in phosphoric acid can also be condensed with alcohols to form phosphate esters. The oxygen from the alcohol molecule bonds with the phosphorus to generate the phosphate ester linkage (Scheme 3). Since phosphoric acid has three –OH groups, it can form a mono-, di- or triester with one, two or three alcohol molecules (regardless of whether the alcohols’ structures are the same or different). Different types of phosphate esters play important roles in cell metabolism (e.g. adenosine triphosphate [ATP] and nucleic acid structures [e.g. RNA and DNA]).
