Oxetenes, electrocyclic ring-opening

A thermal rearrangement of 2-methyleneoxetanes to a,-unsaturated methylketones has been reported, and on heating, the oxetenes formed undergo electrocyclic ring opening to give methyl vinylketones (Scheme 43). ... [Pg.534]

The initial product of this reaction is the hetero [2 + 2] oxetene adduct (41), which then undergoes an electrocyclic ring opening to give the alkene product (Equation 26). [Pg.201]
