Ethyl 4′-amino-5′,8′-dimethyl-1′H-spiro[cyclopentane-1,2′-naphthalene]-3′-carboxylate reacted with allyl isothiocyanate to give 3-allyl-7,10-dimethyl-2-sulfanylidene-2,3,5,6-tetrahydrospiro[benzo[h]quinazoline- 5,1′-cyclopentan]-4(1H)-one. Reactions of the latter with alkyl halides and hydrazine hydrate and subsequent transformations of the products afforded a series of new benzo[h]quinazoline derivatives
乙基4'-氨基-5',8'-二甲基-1' ħ -螺[环戊烷-1,2'-萘] -3'-羧酸乙酯与异硫氰酸烯丙酯反应,得到3-烯丙基-7,10-二甲基2-亚磺酰基-2,3,5,6-四氢螺并[苯并[ h ]喹唑啉-5,1'-环戊烷] -4(1 H)-。后者与卤代烷和水合肼的反应以及产物的后续转化提供了一系列新的在3-位含有烯丙基的苯并[ h ]喹唑啉衍生物。
