Ring and side chain substituted 3-phosphonomethylcyclohexenones react
with triazidochlorosilane (TACS) in acetonitrile or azidotrimethylsila
ne (TMS-N-3)/iodine/pyridine mixture in dichloromethane to afford ring
expanded tetrazolo and gamma-iodo-delta-ketoalk-2-enylphosphonate sys
tems, respectively.
