Abstract

The readily accessible 2-halogeno-1-trimethylsilyloxy-1,3-butadienes, e.g. CH2:CRCR1:CHOSiMe3 (R = H, Me; R1 = F, Cl) react smoothly with MeO2CC.tplbond.CCO2Me to afford 4-halophthalic esters, e.g. I. I (R = H, R1 = Fl) was subsequently converted into the isobenzofuran analog II of phantolide like musk fragrances by Grignard methylation, cyclization, and acetylation. [on SciFinder (R)]

Methylation

In the chemical sciences, methylation denotes the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group. Methylation is a form of alkylation, with a methyl group replacing a hydrogen atom. These terms are commonly used in chemistry, biochemistry, soil science, and the biological sciences. In biological systems, methylation is catalyzed by enzymes; such methylation can be involved in modification of heavy metals, regulation of gene expression, regulation of protein function, and RNA processing.

Forced conversion

Forced conversion is the adoption of a different religion or the adoption of irreligion under duress. Someone who has been forced to convert to a different religion or irreligion may continue, covertly, to adhere to the beliefs and practices which were originally held, while outwardly behaving as a convert. Crypto-Jews, crypto-Christians, crypto-Muslims and crypto-Pagans are historical examples of the latter. In general, anthropologists have shown that the relationship between religion and politics is complex, especially when it is viewed over the expanse of human history.

Aroma compound

An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose. As examples, various fragrant fruits have diverse aroma compounds, particularly strawberries which are commercially cultivated to have appealing aromas, and contain several hundred aroma compounds.
