An exceptionally short and simple enantioselective total synthesis of pentacyclic triterpenes of the β-amyrin family

A new and very direct enantioselective total synthesis of members of the β-amyrin family of pentacyclic triterpenes has been developed starting with acylsilane 5, 2-propenyllithium, and cyclohexenylmethyl bromide 6, which were assembled to form tetraene 7
