Description:
Treatment of {[(benzyloxy)carbonyl]amino}-substituted sulfones 1 with 2-[(trimethylsilyl)oxy]furan ( 2 ) in the presence of InCl 3 as a catalyst at room temperature produced the γ -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 .
