摘要

Abstract Intramolecular [Pd 2 (dba) 3]/tri (2-furyl) phosphine-catalysed (dba= dibenzylideneacetone, PhCH [DOUBLE BOND] CHCOCH [DOUBLE BOND] CHPh) cyclisations of olefinic propargylic carbonates I provided alk-1-enyl-(3-aza) bicyclo [3.1. 0]- hexanes VIII in good yields. A palladium cascade sequence I [RIGHTWARDS ARROW] II [RIGHTWARDS ARROW] III [RIGHTWARDS ARROW] IV [RIGHTWARDS ARROW] VII [ ...
