(2007) demonstrated the highly selective, hydrolysis free O-acylation of alcohols using subcritical water (Scheme 10). Employing a reaction temperature of 200 °C, a pressure of 5 MPa, the acylation of benzyl alcohol 35 was achieved in <10 s, using acetic anhydride 37 as the acylating ...
This work describes the integration of multi-step enzymatic pathway construction with enzyme kinetics and bioreactor modelling, in order to optimise the synthesis of chiral amino-alcohols using engineered Escherichia coli transketolases (TK) and the Chromobacterium violaceum transaminase (TAm). The ...
The reaction is of very broad scope, and hundreds of alcohols have been prepared in this manner. R may be alkyl or aryl. In many cases the hydrolysis step is carried out with dilute HCl or H2SO4, but this cannot be done for tertiary alcohols in which at least one alkyl group is ...

THE CARROLL REACTION (II) C3 units are added by the thermal reaction of tertiary propargylic or allylic alcohols with ethyl acetoacetate, a reaction known by the name of its discoverer Carroll. The reaction yields ketones (Figure 8). Lack of time prevents me from going into details of the ...

alcohols, ether, ethyl acetate and methylene chloride when used gave either no crystals or gave a product with a lower LC purity (96–99%). Thus it was concluded that acetone is the ideal solvent for recrystallization of alfentanil HCl even though the recovery yield was only 76–80%. Analys...
In yet another embodiment of the invention, the reaction may be initiated with one alcohol and continued with another, or with a mixture of alcohols. Thus, in an embodiment of the invention, copper-activated silicon prepared with nanosized copper catalyst precursors can be reacted initially with...
Suitable solvents or diluents include, but are not limited to: alcohols, preferably C1 -C5 alcohols such as ethanol; water and aqueous solutions suitable for parenteral administration to a patient such as Sterile Water for Injection, USP, Normal Saline, USP, and 5% Dextrose in Water, USP; ...
