Three unsymmetrically substituted polyamine analogues demonstrate significant and selective antitumor effects.

The use of an unsymmetrically substituted analog could provide the necessary evidence.
|
|
The blowhole was large and somewhat unsymmetrically placed, the right angle being the more anterior.
|
|
Optically active unsymmetrically substituted cyclic sulfites are especially useful in the synthesis of other optically active compounds.

|
At the east end a door, unsymmetrically placed, leads to the small chapel which was originally the prothesis.
|
|
The hydrosilylation of unsymmetrically substituted olefins could potentially result in two possible isomers, namely Markovnikov and anti-Markovnikov products.
|
|
The use of other new analogs, such as the unsymmetrically substituted analogs mentioned above, could shed light on such issues.

Lock the boom swing compensation in preset or desired boom height before the boom sides are folded out or in unsymmetrically.

|
Lock the boom swing compensation in the pre-set respectively desired boom height before the side arms of the boom are folded out or in unsymmetrically.

With its huge ungainly limbs sprawling unsymmetrically, and its gnarled hands and fingers, it stood an aged, stern, and scornful monster among the smiling birch trees.
|
|
If your glider wants to turn to one side the cause is often an unsymmetrically adjusted harness or the effect of a side mounted reserve as well.

Railway wagon wheel load balance for the detection of the load of each wheel of fast moving trains to identify unsymmetrically loaded wheels of incorrectly charged wagons or wagons with a defective wheel suspension.

Later, when Metabee and the other Medabots helped Kam, who was injured, Gryphon as Blakbeetle saved them when the roof collapsed. It is unknown if the body of Gryphon was destroyed by the fire. Gryphon was designed somewhat unsymmetrically, with a big head and small body, but possesses great destructive power.

Ethyl 2-methylacetoacetate (R=R'=Me) gives the geometrically pure E isomer by this method. center Simple aldehydes and ketones react with NfF in the presence of bases such as DBU or phosphazenes to give alkenyl nonaflates in high yields without formation of a discrete enolate. Use of the P2 phosphazene base at -30 to -20 °C gives the less substituted alkenyl nonaflate with unsymmetrically substituted ketones. Similar reactions with triflic anhydride generally require the use of the expensive 2,6-di-tert-butylpyridine to achieve high yields.
