Synthesis and evaluation of analogs of Efavirenz (SUSTIVATM) as HIV-1 reverse transcriptase inhibitors
摘要:
Efavirenz (SUSTIVA(TM)) is a potent non-nucleoside reverse transcriptase inhibitor. Due to the observation of breakthrough mutations of the reverse transcriptase enzyme during Efavirenz therapy, we sought to develop an optimized second generation series. To that end, SAR of the substituents on the aromatic ring was undertaken and the results are summarized here. The 5,6-difluoro (4f) and the 6-methoxy (4m) substituted benzoxazinones were determined to be equipotent, and as a result such substitution patterns will be incorporated in second generation scaffolds.

ortho-selective C–H halogenation methodology is reported herein. The highlight of the work is the highly selective C(sp2)–H functionalization of benzyl nitriles in the presence of activated C(sp3)–H bond, which results in good yields of the halogenated products with excellent regioselectivity. Along with benzyl nitriles, aryl Weinrebamides and anilides have been evaluated for the transformation using aprotic

Enantioselective C–Pcross-coupling of diarylphosphine oxides with ortho-substituted aryl iodides has been achieved via kinetic resolution strategy, affording chiral triarylphosphine oxides in high yields and with moderate to high enantioselectivity.
