title: Internal chirality transfer in the reaction of substituted cyclic (S,O)-ketene ortho esters with aldehydes catalysed by Lewis acid.
abstract: Internal chirality transfer of 1a and 1b with aldehydes in the presence of Lewis acid catalyst resulted in high diastereoselectivities in the construction of a highly functionalised acyclic system.
