Amino alcohols constitute a very useful and versatile class of organic compounds, with important applications in synthetic and medicinal chemistry. However, in most of the procedures described in the literature for the obtainment of these compounds, considerable limitations can be found, such as drastic conditions, long time reactions, poor yields, and purification problems. The present article describes a methodology that gives amino alcohols and N-protected amino alcohols based on the reduction of amino acid esters under mild conditions, employing NaBH4 in the presence of methanol. The reactions occurred in a short time (15-20min) and provide yields of 50-95%.
An improved synthesis of solid-supported reagents (SSRs) for selective acylation of amines by microwave irradiation
Petricci, Elena,Botta, Maurizio,Corelli, Federico,Mugnaini, Claudia
, p. 6507 - 6509 (2002)
Microwave-assisted acylation of a solid-supported pyrimidine linker with different acyl chlorides gave polymer-bound 4-acyloxypyrimidines, which in turn were used as SSRs for rapid and selective acylation of amines under microwave irradiation.
Chemoselective Synthesis of α-Amino-α-cyanophosphonates by Reductive Gem-Cyanation-Phosphonylation of Secondary Amides

A novel approach to α-amino-α-cyanophosphonates has been developed. The method features a Tf2O-mediated reductive geminal cyanation/phosphonylation of secondary amides. Mild reaction conditions, high bond-forming efficiency, inexpensive readily available starting materials, and good to excellent yields with wide functional group compatibility constitute the main advantages of this method. The protocol can be run on a gram scale.
Targeting dopamine D3 and serotonin 5-HT1A and 5-HT2A receptors for developing effective antipsychotics: Synthesis, biological characterization, and behavioral studies

Combination of dopamine D3 antagonism, serotonin 5-HT1A partial agonism, and antagonism at 5-HT2A leads to a novel approach to potent atypical antipsychotics. Exploitation of the original structure-activity relationships resulted in the identification of safe and effective antipsychotics devoid of extrapyramidal symptoms liability, sedation, and catalepsy. The potential atypical antipsychotic 5bb was selected for further pharmacological investigation. The distribution of c-fos positive cells in the ventral striatum confirmed the atypical antipsychotic profile of 5bb in agreement with behavioral rodent studies. 5bb administered orally demonstrated a biphasic effect on the MK801-induced hyperactivity at dose levels not able to induce sedation, catalepsy, or learning impairment in passive avoidance. In microdialysis studies, 5bb increased the dopamine efflux in the medial prefrontal cortex. Thus, 5bb represents a valuable lead for the development of atypical antipsychotics endowed with a unique pharmacological profile for addressing negative symptoms and cognitive deficits in schizophrenia.
