, (2017/02/28)
Provided herein (among other things) are protease inhibitor compounds having enhanced features, along with methods for administering such compounds. For example, the subject compounds can be administered without concomitant administration of a CYP3A4 inhibitor, have increased therapeutic index and/or increased potency, and are low-resistance inducing in nature.

An efficient and practical synthesis of the HIV-1 protease inhibitor Atazanavir was developed by employing the diastereoselective reduction of ketomethylene aza-dipeptide isostere 10 as the key and final step. The high diastereoselectivity of the amino ketone reduction by lithium tri-iert-butoxyaluminum hydride in diethyl ether to afford the desired svn-1,2-amino alcohol structure was achieved by Felkin- Anh control as a result of the bulky and chiral N-(methoxycarbonyl)-L-tert-leucinyl moiety as the nitrogen protecting group. The coupling of the two key intermediates, N-(methoxycarbonyl)-L-tert-leucine acylated benzyl hydrazine 7 and chloromethyl ketone 9, via an SN2 reaction furnished the amino ketone 10 in high yield under our optimized conditions. Our new methodology features the late introduction of the S-hydroxyl group and the early acylation of benzyl hydrazine and chloromethyl ketone with N-(methoxycarbonyl)-L-tert-leucine, respectively, which confers high efficiency and easy purification.
