Abstract

The THP ether of 4,5-dihydro-3-nitro-4-isoxazolol, prepared by a sequential nitroaldol nitrosative cyclization strategy, was converted to a 4,5-dihydro-3-(dithiolanyl)isoxazole; subsequent LBH reduction gave a 95:5 diastereomeric mixture of 2-deoxy-2-aminothreose and -erythrose derivatives, respectively, which was cyclized to a mixture of tetrahydro-2H-1,3-oxazine-2-ones. A 3-nitro-4-oxygenated isoxazoline, prepared from CICH2CHO in 28% overall yield, was transformed to a 3-(dithiolanyl)isoxazoline. Reduction afforded γ-amino-alcohols (1–92 d.e.) and a spirotetrahydrofuran. [Display omitted]
