It is the parent of many related compounds with more complex structures. For example, [[psoralen]] is a benzofuran derivative that occurs in several plants. It is prepared by ''O''-alkylation of [[salicylaldehyde]] with chloroacetic acid followed by [[Dehydration reaction|dehydration]] of the resulting [[ether]].<ref>Albert W. Burgstahler and Leonard R.
