## Abstract The structure and synthesis of novel irregular C~12~ terpenoids isolated from quince fruit (__Cydonia oblonga__ MILL.) are described: quince oxepine (= (__E__)β2,3,6,7βtetrahydroβ4βmethylβ2β(3βmethylbutaβ1,3 dienyl)oxepine; 3) and the quince oxepanes as a 1:1 mixture of __cis__β and __t
