Ynones and ynals bearing a variety of substituent were converted into isotellurazole Te-oxide oligomers through a convenient procedure via formation and ring closure of beta-(N,N-dimethylcarbamoyltellurenyl)alkenyl ketones or aldehydes, and the subsequent conversion of A into the corresponding isotellurazoles B was carried out efficiently by treating with Ph3P/I-2 under a rather mild reaction condition.
