Organic Synthesis Via Examination of Selected Natural Products
Compounds of type 198 (Prostaglandins-25) and 206 (Prostaglandins-26) are
known as geminally activated cyclopropanes. They are cyclopropanes with two
electron-withdrawing groups positioned on one of the cyclopropane carbons.

As with the synthesis of trisubstituted azines 4 (see Section 27.16.1.4) the
reaction of hydrazones with an appropriate aldehyde, in this case formaldehyde,
is a precedented approach to the synthesis of geminally disubstituted azines.
