Asymmetric synthesis of aerothionin, a marine dimeric spiroisoxazoline natural product, employing optically active spiroisoxazoline derivative

Successful first synthesis of optically pure (+)- and (-)-aerothionins (1) from the racemic spiroisoxazoline derivative 8 has been accomplished. The absolute configuration of natural (+)-1 was determined by comparison of (+)- and (-)-8 with related derivatives. (c) 2005 Elsevier Ltd. All rights reserved.
