Abstract
Alcohol is ubiquitous with unparalleled structural diversity and thus has wide applications as a native functional group in organic synthesis. It is highly prevalent among biomolecules and offers promising opportunities for the development of chemical libraries. Over the last decade, alcohol has been extensively used as an environmentally friendly chemical for numerous organic transformations. In this review, we collectively discuss the utilisation of alcohol from 2015 to 2023 in various organic transformations and their application toward intermediates of drugs, drug derivatives and natural product-like molecules. Notable features discussed are as follows: (i) sustainable approaches for C-X alkylation (X = C, N, or O) including O-phosphorylation of alcohols, (ii) newer strategies using methanol as a methylating reagent, (iii) allylation of alkenes and alkynes including allylic trifluoromethylations, (iv) alkenylation of N-heterocycles, ketones, sulfones, and ylides towards the synthesis of drug-like molecules, (v) cyclisation and annulation to pharmaceutically active molecules, and (vi) coupling of alcohols with aryl halides or triflates, aryl cyanide and olefins to access drug-like molecules. We summarise the synthesis of over 100 drugs via several approaches, where alcohol was used as one of the potential coupling partners. Additionally, a library of molecules consisting over 60 fatty acids or steroid motifs is documented for late-stage functionalisation including the challenges and opportunities for harnessing alcohols as renewable resources.

Abstract
Whereas iron catalysts usually promote catalyzed C3-alkylation of indole derivatives via a borrowing-hydrogen methodology using alcohols as the electrophilic partners, this contribution shows how to switch the selectivity towards N-alkylation. Thus, starting from indoline derivatives, N-alkylation was efficiently performed using a tricarbonyl(cyclopentadienone) iron complex as the catalyst in trifluoroethanol in the presence of alcohols leading to the corresponding N-alkylated indoline derivatives in 31-99 % yields (28 examples). The one-pot, two-step strategy for the selective N-alkylation of indolines is completed by an oxidation to give the corresponding N-alkylated indoles in 31-90 % yields (15 examples). This unprecedented oxidation methodology involves an iron salt catalyst associated with (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) and a stoichiometric amount of t-BuOOH at room temperature.

Abstract
Aims:
A green route for the oxidation of alcohols to corresponding carbonyl compounds in room temperature ionic liquid ([CEMIM]BH4) was developed by using hydrogen peroxide as the oxygen source. In aqueous solution at room temperature, 0.2 mol% of ([CEMIM]BH4) showed excellent catalytic properties for selective oxidation of aromatic and aliphatic alcohols
Background:
One of the vital reactions in organic synthesis is the oxidation of alcohols to carbonyl compounds. In particular, the conversion of primary alcohols to aldehydes has received a variety of applications as they are used as intermediates in fine chemicals mostly for the perfume industry.
Objective:
In the present work, we have reported an effective green route for the selective oxidation of alcohols to the carbonyl compounds using peroxide in an ionic liquid 1-carboxyethyl-3-methyl-imidazolium tetrahydroborate ([CEMIM]BH4)
Methods::
A mixture of alcohol (2 mmol), ([CEMIM]BH4) (0.2 mol%), H2O2 (2 mmol) were stirred thoroughly with the help of a magnetic stirrer for 10 min at ambient temperature
Results:
The catalytic activity of ([CEMIM]BH4) is very effective, which reflects its good solvating nature during the oxidation.
Conclusion:
In conclusion, the series of experiments described represents a useful method for the oxidation of primary and secondary alcohols to carbonyl compounds at room temperature. The catalyst can be easily prepared and is therefore extremely cost-effective. The rapid reaction times for the substrates mean a large number of materials may be screened in parallel over a short period of time.
