Facile Synthesis of 3-Aroyl-3-Sulfolenes Through Cycloadditions of Arylnitrile Oxides & 3-Sulfolene
摘要:
3-Sulfolene undergoes [2+3] cycloadditions with arylnitrile oxides to yield the corresponding 2-isoxazolines which on cleavage in the presence of Mo(CO)(6) followed by dehydration gave 3-aroyl-3-sulfolenes in moderate yields.

2-(N-Nitrosomethylamino-oxy)ethyl ketones (3), obtained from solvolysis with sodium nitrite of N-methyl-4,5-dihyroisoxazolium methylsulphates (2), were converted into α,β-unsaturatedketones (4) by treatment with base or into β-hydroxyketones (5) by treatment with carboxylic acids.
