Racemic N-methyl-S-(nitromethyl)-S-phenylsulfoximine (2) was prepared in 87% yield via alkaline nitration of N,S-dimethyl-S-phenylsulfoximine. Optically active N-methyl-S-(nitromethyl)-S-phenylsulfoximine (both enantiomers) was prepared in similar fashion. Reaction of racemic 2 with p-chlorophenyl isocyanate and a catalytic quantity of triethylamine in the presence of furan afforded dihydrofuroisoxazole
