protected cysteine readily provided the hemi-thioacetals 9a and 11a related to leukotriene-E4. Use of acetylene-bis-(diethyl acetal) 12 led to a facile synthesis of the title compound 17a. Its corresponding hexahydro analogs displayed marked antagonist activity against LT-C4 induced contractions on isolated guinea pig lung parenchyma.
