Abstract
Compounds 4a-4d, 4f and 10 were prepared and their ring-opening reacti ons with N-bromosuccinimide (NBS) investigated. Compounds 4a and 4b ga ve a mixture of products which did not contain any significant quantit y of the corresponding aldehydes 5a and 5b whereas compounds 4c, 4d an d 4f gave exclusively the aldehydes 5c, 5d and 5f respectively. Compou nd 10 similarly gave the aldehyde 11 when treated with NBS.
