HAMMETT-CORRELATIONS, SOLVENT EFFECTS AND STEREOCHEMISTRY OF THE THERMAL DECARBOXYLATION OF 2-OXETANONES - EVIDENCE FOR A ZWITTERIONIC INTERMEDIATE

Kinetic and stereochemical data of the thermal decarboxylation of 2-oxetanones (1 and 2) indicate that the reaction proceeds via a zwitterionic intermediate Z.

Cis-cinnamic acid analogue, gravitropism modifier (by machine translation)

[Problem] cinnamic acid or cinnamic acid analogue comprising adjusting agent gravitropism cis. [Solution] cinnamic acid and/or cinnamic acid as an active ingredient to adjust gravitropism cis edge agents, cinnamic acid edge is, for example obtained by reacting compounds of the following formula. (In the formula, R is a phenyl group. )Figure 6 [drawing] (by machine translation)

Cp2TiCl2-catalyzed hydrocarboxylation of alkynes with CO2: formation of α,β-unsaturated carboxylic acids

Cp2TiCl2-catalyzed hydrocarboxylation of alkynes with CO2 (atmospheric pressure) has been reported. A range of alkynes were transformed to the corresponding α,β-unsaturated carboxylic acids in high yields with high regioselectivity. The reaction proceeded with hydrotitanation, transmetalation, and subsequently carboxylation with CO2

CIS CINNAMIC ACID ANALOG AND GRAVITROPISM MODIFIER

PROBLEM TO BE SOLVED: To provide a gravitropism modifier having effects on creeping property of plants or sugar content of fruits. SOLUTION: There is provided a gravitropism modifier containing cis cinnamic acid and/or a cinnamic acid analog represented by the formula (1) as active ingredients. (1), where A is cyclic hydrocarbon which may have a substituent, X is a bound or a C1 to 5 substituted or unsubstituted hydrocarbon chain, R1 is H, a hydroxyl group, an alkali earth metal salt or the like, R2 is a bond or a C1 to 5 substituted or unsubstituted hydrocarbon chain and R3 and R4 are H or together form C5 to 8 cyclic hydrocarbon.
