title: Me3SiI-promoted reaction of salicylic aldehydes with ketones: a facile way to construct benzopyranic [2,3-b]ketals and spiroketals.
abstract: Me(3)SiI-promoted reaction of salicylic aldehydes with ketones via arylmethylation at the α-site of the carbonyl group and cyclodehydration of keto-diol provided a facile way to construct heteroannular ketals, furnishing benzopyranic [2,3-b]ketals and spiroketals in moderate to good yields.
