Photolysis (A = 254 nm) of 4-(tert-butyl)-4,6,7,8-tetrahydro-7,7-dimethyl-2H-l-benzopyran-2,5(3H)-dione (3a) in t-BuOH affords 2-(2,2-dimethylpropylidene)-5,5-dimethyl-l,3-cyclohexanedione (la) in 80% yield via homolysis of the lactone 0-CO bond and subsequent ketene elimination.

## Abstract Acetolysis of diazoketone **1** gives in good yield 6‐acetoxy‐tricyclo[3.3.0.0^2,8^]octan‐3‐one (**2**) which is converted into semibullvalene in a three‐step sequence. Compound **2** is potentially a good starting material for 3,6‐substituted semibullvalenes.
## Abstract The unusual propellane skeleton of the sesquiterpene modhephene (**1**) has been synthesized starting from cyclopentenone (**2**). The key step **6** → **7** is an efficient and highly stereoselective intramolecular thermal ene‐reaction. Further elaboration of the propellane **7** gave
## Abstract During the reaction of allyl ethers, allyl sulfides and allyl selenides with __in situ__ prepared dichloroketene (**1**), 2 competing pathways are observed. Besides [2+2]‐cycloaddition, an unprecedented [3,3]‐sigmatropic (__Claisen__) rearrangement via a 1,3‐dipolar intermediate takes p
## Abstract In der vorliegenden Mitteilung wird erstmals ein Zugang zu __trans__‐N‐Acyl,N‐alkyl‐1‐amino‐1,3‐butadienen **4**, sowie zu __trans__‐N‐Acyl, N‐aryl‐1‐amino‐1,3‐butadienen **4** beschrieben. Deprotonierung von N‐substituierten 1‐Imino‐2‐butenen **2** führt vermutlich zu den nicht isolier
