A modular, efficient, and practical methodology for the preparation of 4- and 3-substitutedbenzene and anilineC-ribonucleosides was developed. Addition of 4- or 3-bromophenyllithium (2 or 12) to TBDMS-protected ribonolactone 3 gave hemiacetal adducts 4 or 13 as pure β-anomers. Their reduction with Et3SiH and BF3·Et2O afforded the desired protected 4- or 3-bromophenyl-C-ribonucleosides 6 or 15 in
