## Abstract The glycosylation of indazolyl anions derived from 4a, b with 2‐deoxy‐3,5‐bis‐__O__‐(4‐methylbenzoyl)‐α‐D‐__erythro__‐pentofuranosyl chloride (5) is described. The reaction was Stereoselective – exclusive β‐D‐anomer formation – but regioisomeric __N__^1^‐ and __N__^2^‐(2′‐deoxy‐β‐D‐ribo
