Abstract

New 5′‐acetyl‐3′‐1,3,4‐thiadiazoliminothymidines 11, 14 were prepared, via spontaneous rearrangments, by cycloaddition of 5′‐acetyl‐3′‐deoxy‐3′‐isothiocyanatothymidine 9 with 1‐aza‐2‐azoniaallene hexachloantimonates. Similary, 3′‐cyano analogue 19 was reacted with the same cumulenes to furnish 3′‐1,2,4‐triazolo‐thymidines 22, 24, and 26. Deblocking of the acylated products afforded the free nucleosides. © 2003 Wiley Periodicals, Inc.

## Abstract The reaction of N‐aryl‐C‐ethoxycarbonyl nitrilimines with [1,2,4]triazepin‐3,5‐dithione leads to title compounds. The 1,3‐dipolar cycloaddition is completely peri and regioselective. The preferred orientation of addition is predicted correctly by AM~1~ calculation.
