Indium(III) Chloride-Catalyzed Conversion of {[(Benzyloxy)carbonyl]amino}-Substituted Sulfones with 2-[(Trimethylsily)oxy]furan: A Facile Access to gamma-Butenolactone Derivatives Containing a Protected Amino Group)
[摘要]：Treatment of {[(benzyloxy)carbonyl]amino}-substituted sulfones 1 with 2-[(trimethylsilyl)oxy]furan (2) in the presence of InCl3 as a catalyst at room temperature produced the gamma-butenolactone derivatives 3 and 4 containing a protected amino group (Scheme 1). The products were formed in high yields (81-92%) within 3-10 h favoring the anti-isomer 3.
