讨论了第五部分中描述的光环化过程对A环取代的化合物的应用。将光环化产物12-亚乙二氧基-6a α，7，12，12 a α-四氢-9，11-二甲氧基-6-氧代-1-苯基-6H-萘并[1，12-bc]呋喃-10-甲酸甲酯（XII; R1= Me，R2= OMe，X = Y = O）转化为6-甲基预四酰亚胺。
Application of the photocyclisation procedure described in Part V to ring A substituted compounds is discussed. The photocyclisation product methyl 12-ethylenedioxy-6aα,7,12,12aα-tetrahydro-9,11-dimethoxy-6-oxo-1-phenyl-6H-naphthaceno[1,12-bc]furan-10-carboxylate (XII; R1= Me, R2= OMe, X = Y = O) has been converted into 6-methylpretetramid.
