Total synthesis of (+)-halichlorine: An inhibitor of VCAM-1 expression

Research output: Contribution to journalArticlepeer-review


The diastereoselective addition of the highly functionalized organozinc compound 1 to the aldehyde 2 in the presence of the chiral amino alcohol 3 (→4) is a key step in the first total synthesis of (+)-halichlorine. A series of protections/deprotections and a macrolaconization complete the synthesis. Halichlorine selectively inhibits the expression of the cell adhesion molecule VCAM-1. TBS = tertbutyldimethylsilyl.
