Simple, chemoselective, catalytic olefin isomerization

Catalytic amounts of Co(SaltBu,tBu)Cl and organosilane irreversibly isomerize terminal alkenes by one position. The same catalysts effect cycloisomerization of dienes and retrocycloisomerization of strained rings. Strong Lewis bases like amines and imidazoles, and labile functionalities like epoxides, are tolerated.

Kinetic benchmarking reveals the competence of prenyl groups in ring-closing metathesis

A series of prenyl-containing malonates are kinetically benchmarked against the standard allyl-containing congeners using a ruthenium benzylidene precatalyst for ringclosing metatheses. The prenyl grouping is found to be a superior acceptor olefin compared to an allyl group in RCM processes with ruthenium alkylidenes derived from terminal alkenes. The prenyl group is also found to be a highly competent acceptor for a ruthenium alkylidene derived from a 1, 1-disubstituted olefin in a RCM process.

Synthesis of 2,3-Secopyrethroids

Some 2,3-secopyrethroids, viz. 3-phenoxybenzyl 2-alkyl-5-methylhex-4-enoates and 2-alkylpent-4-enoates (VI a-l) have been synthesized starting from diethyl malonate, employing simple reactions like alkylation, decarboethoxylation and transesterification.These esters exhibit insecticidal activity against musca domestica and adult Aedes aegyptii.
