Both the molecules have been synthesized in just two-steps from readily available starting materials.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">1.177</style></custom4></record></records></xml>
