✦ Synopsis

3+2] C-~clnaddifion methodology provides a general and efficient access to 5-alkyl mb~ituted 2(5/-/)furanones. The synthetic approach has been exploited towards the synthesis of naturally oeeurria 8 butenolides.

Cycloadditions of various 1,3-dipolar reagents to chiral butenolides 1 and 2 proceed with diastereomeric excess of 20-100%. Recently we reported a new class of C-4 and C-5 chiral synthons based on
