218. INTRAMOLECULAR CYCLIZATION OF AN AMMONIUM SALT CONTAINING AN ALLYL SUBSTITUENT IN POSITION 1 OF THE DIENE FRAGMENT

Article abstract of DOI:10.1007/BF01165010

It has been shown that, under basic catalytic conditions, dimethylpropargylallyl-(1-allyl-3-phenylpropargyl)- and -(1-allyl-3-α-naphthylpropargyl)ammonium salts undergo diene synthesis type intramolecular cyclization to form condensed analogs of isoindolenium and dihydroindolenium salts with an allyl substituent at position 1.
