acids. Intramolecular acylation of these acids in the presence of trifluoroacetic anhydride is shown to be dependent on the structure and stereochemistry of the acids. The formation of cyclohept-2-enone from hept-6-enoic acid is reported. Concentrated sulphuric acid in acetic anhydride is shown to convert hex- and hept-5-enoic acid into phenyl and o-tolyl acetate, respectively. Some improved syntheses

There is provided a process for producing a bicyclo [3.1.0] hexane derivative represented by the formula (I) and a salt thereof including; causing an enzyme to act on an optically inactive compound represented by the formula (II) causing an asymmetric acylation reaction and a highly-stereoselective conversion to an optically active compound represented by the formula (III); and converting the compound represented by the formula (III) to the compound represented by the formula (I) or a salt thereof.
stereoselective total synthesis of (+)-pentalenene was achieved through the tandem cycloaddition reaction of the allenyl diazo substrate prepared from (+)-citronellal. The initial intramolecular [2+3] cycloaddition reaction between the diazo functionality and the allenyl group produced the trimethylenemethane (TMM) intermediate after immediate loss of nitrogen molecule from the cycloaddition intermediate.

The present invention relates to a process for preparing fused tetrahydro-[
1
H]-triazoles of the formula I
1
where the variables R
a
, Z, Z
1
, X, W, n and Q are as defined in claim 1, by cyclization of compounds of the formula II
2
where R is C(X)OR
2
or C(X)SR
2
, where X is oxygen or sulfur, and R
2
is as defined in claim 1, in the presence of a base.
The invention also relates to compounds of the formula I where W is sulfur if Z is a methylene group optionally substituted by R
a
, and furthermore to compounds of the formula I where Q is a benzoxazole or benzothiazole radical, and to the use of these compounds as herbicides.
