In other words, it involves the combination of more abstract units of meaning than derivational synthesis. [3] In the following examples many of the morphemes are related to voice (e.g. passive voice), whether a word is in the subject or object of the sentence, possession, plurality, or other abstract distinctions in a language: Italian
Convergent synthesis or linear synthesis, a strategy to improve the efficiency of multi-step chemical syntheses Dehydration synthesis , a chemical synthesis resulting in the loss of a water molecule Biosynthesis , the creation of an organic compound in a living organism, usually aided by enzymes
Medicine: Organic synthesis plays a vital role in drug discovery, allowing chemists to develop and optimize new drugs by modifying organic molecules. [9] Additionally, the synthesis of metal complexes for medical imaging and cancer treatments is a key application of chemical synthesis, enabling advanced diagnostic and therapeutic techniques. [10]
Enantioselective synthesis, also called asymmetric synthesis, [1] is a form of chemical synthesis.It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereomeric) products in unequal amounts."
Robert Burns Woodward, who received the 1965 Nobel Prize for Chemistry for several total syntheses [5] including his synthesis of strychnine, [6] is regarded as the grandfather of modern organic synthesis. [7] Some latter-day examples of syntheses include Wender's, [8] Holton's, [9] Nicolaou's, [10] and Danishefsky's [11] total syntheses of the ...
Another way to achieve a high degree of synthesis is when languages can form compound words by incorporation of nouns, so that entire words can be incorporated into the verb word, as baby is incorporated in the English verb babysit. Another common feature of polysynthetic languages is a tendency to use head marking as a means of syntactic ...
There is little to no morphological change in words: they tend to be uninflected. Grammatical categories are indicated by word order (for example, inversion of verb and subject for interrogative sentences) or by bringing in additional words (for example, a word for "some" or "many" instead of a plural inflection like English -s). Individual ...
Many retrosynthetic disconnections important for organic synthesis planning use carbocationic synthons. Carbon-carbon bonds, for example, exist ubiquitously in organic molecules, and are usually disconnected during a retrosynthetic analysis to yield carbocationic and carbanionic synthons.
