Synthesis of some 13-oxaprostanoids
Abstract
A new route to biologically interesting 13-oxaprostanoids is described. Reaction of an unhindered secondary hydroxy group with t-butyldiphenylsilyl chloride in the presence of an adjacent hindered hydroxy group allows rapid access to the key synthon (7), from which prostanoids of the F series [e.g. compound (13)] and I series [e.g. compound (18)] were prepared.
