Dolutegravir, a second-generation HIV Integrase Strand Transfer Inhibitor (INSTI), is the most current antiretroviral ratified for treatment of HIV-1 infection. This approval is based on the superiority of Dolutegravir in clinical trials over the well-known antiretroviral marketed drugs like Efavirenz, Raltegravir, and Darunavir. Largely, Dolutegravir has established excellent tolerability, limited drug interactions, insignificant drug resistance and once-daily dosing for treatment-naive patients. (R)-3-amino butanol is a key unit for the synthesis of Dolutegravir and rarer methods of synthesis are mentioned in the literature.
