Besides the potential health risk incurred when using hazardous reagents such as diazomethane or dimethyl sulfate, the alkylation method is subject to interferences from other compounds with active H-atoms, e.g., carboxy acid herbicides such as 2,4-dichloro-and 2,4,5-trichlorophenoxyacetic acid (Chau & Coborn, 1974; Crosby et al., 1981).

At pH 5, 33.39% of PCP is in the molecular form, while, at pH 8, more than 99% exists as phenate ion.

Trimethylsilyl diazomethane synthesis essay - …

The 1,3-dipolar cycloadditions of trimethylsilyl diazomethane with camphorsultam-derived acrylates are reported as a means for the efficient synthesis of optically active pyrazolines. Trimethylsilyl diazomethane is a safe, commercially available diazoalkane which provides Δ1-pyrazolines 1n good yield and diastereoselectivity when camphorsultam-derived acrylates are used as the reaction dipolarophiles . These initial cycloadducts are subsequently converted to stable, characterizable Δ2-pyrazolines upon desilylation.

A 5-step synthesis of α-alkoxymethyl-, α-siloxymethyl- and α-(carbamoyloxy)methyl-substituted enediynes 7 from type 23 β-oxo esters was developed following the strategy of Scheme 2. Specifically, the β-oxo esters 33, 36 and 38 (prepared as shown in Scheme 4) and NaH (or t-BuLi) gave Z-enolates in THF and E-enolates in DMF which were scavenged as enol triflates Z-27a-c and E-27a-c, respectively, upon treatment with triflimides 40 or 41 (Scheme 5). The Z-configurated enol triflates underwent Cacchi couplings with (trimethylsilyl)acetylene to give the pent-2-en-4-yne-1-carboxylates E-42a-c (Scheme 5). These were reduced to the corresponding aldehydes E-44a-c (Scheme 6) which were homologated with lithio(trimethylsilyl)diazomethane to furnish the desired enediynes 45a-c as pure E-isomers.
