## Abstract We report the synthesis of a class of 4‐(2‐oxoethylidene)azetidin‐2‐ones by a novel Lewis acid mediated reaction of acyldiazo compounds with 4‐acetoxyazetidin‐2‐ones. Using this approach, C‐3‐and C‐4‐substituted 4‐alkylideneazetidin‐2‐ones were obtained depending on the choice of starti
## Abstract Alkyl 2‐nitroacetates **2** react with alkyl phenylpropiolates **1** in the presence of Ph~3~P in a mechanistically novel reaction to afford trialkyl 3‐phenylbuta‐1,3‐diene‐1,2,4‐tricarboxylates in yields of 60–80% under neutral conditions.
## Abstract Stereospecific synthesis of a family of novel (__E__)‐2‐aryl‐1‐silylalka‐1,4‐dienes or (__E__)‐4‐aryl‐5‐silylpenta‐1,2,4‐trienes via a cross‐coupling of (__Z__)‐silyl(stannyl)ethenes with allyl halides or propargyl bromide is described. In the reaction with allyl bromide, either a Pd(db
