A step in a synthesis of PGE1 (prostanglandin E1, alprostadil) is reaction of a trisubstituted cyclohexene with bromine to form a bromolactone. Alprostadil is used as temporary therapy for infants born with congenital heart defects that restrict pulmonary blood flow. It brings about dilation of the ductus arteriosus, which in turn increases blood flow in the lungs and blood oxygenation.
Propose a mechanism for formation of This bromolactone, and account for the observed stereochemistry of each substituent on the cyclohexane ring.
Give a step-by-step mechanism for the following substitution reactions:
