| Abstract: | In the presence of SnCl(4) and Et(3)N, intramolecular carbostannation reaction of various active methine compounds having an unactivated alkenyl, alkynyl, or allenyl group proceeds in good yields with complete regioselectivity. The subsequent reaction of the resulting Sn intermediates with some electrophiles provides functionalized cyclopentane and cyclohexane derivatives. |
