Abstract
A complex cascade involving allendiynes in the presence of a cationic gold catalyst is described. The process features two sequential acyl-group shift/cyclization steps eventually delivering a bicyclic furan derivative from the acyclic precursor. A controlled sequence of molecular events can thus readily deliver the desired heterocycle with a remarkable selectivityFile in questo prodotto:
