Stereoselectivity in the Peterson reaction - application to the synthesis of BRL 49467.
摘要:
The E:Z selectivity in the introduction of the tri-substituted double bond in BRL 49467 could be controlled by the choice of base and silyl group used in a Peterson olefination reaction. The method allowing optimum E-selectivity was developed such that it could be scaled up to 100mmol.
