Cascade radical-mediated cyclisations with conjugated ynone electrophores. An approach to the synthesis of steroids and other novel ring-fused polycyclic carbocycles
Pattenden, Gerald,Stoker, Davey A.,Thomson, Nicholas M.
, p. 1776 - 1788 (2008/02/10)
A cascade radical-mediated Diels-Alder reaction with the iododienynone 16b produced the tricyclic ketone 17 (22%). By contrast, treatment of the substituted furans 36 and 47 with Bu3SnH-AIBN, instead led to the tetracycles 44 and 58 respectivel
An attempted cascade radical-mediated cyclisation approach to ring-D aromatic steroids
Pattenden, Gerald,Blake, Alexander J.,Reddy, L. Krishnakanth,Stoker, Davey A.
, p. 3073 - 3076 (2008/02/13)
A synthetic approach to ring-D aromatic steroids, viz. 5, based on a cascade of radical-mediated cyclisations from the ortho-aryl-substituted iododienynones 12 and 13, instead led to the macrocyclic ketone 16 or to the novel bridged tricycle 17, respectively, as the major products.
