Abstract
(BuOK)-O-t-promoted reaction of prop-2-ynyl alcohols 5 or N-methylprop -2-ynylamine 12 with nitroalkenes 1-4 affords 3-methylenetetrahydrofur ans 6-9 and 3,4-dihydropyrans 10 and 11 or 3-methylenepyrrolidines 13- 16, respectively, in moderate to good yields, with total allylic 1,3-s train-controlled diastereoselectivity.
