2-(But-3-yn-1-yloxy)tetrahydro-2H-pyran (cas: 40365-61-5) belongs to tetrahydropyran derivatives. Tetrahydropyran is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and dyestuff. 2-(Arylmethylene)cyclopropylcarbinols could be converted to the corresponding tetrahydropyrans stereoselectively in the presence of Brønsted acids under mild conditions. A plausible Prins-type reaction mechanism has been proposed.Recommanded Product: 40365-61-5

Synthesis of the precursor compound of anti-tumor natural product ainsliatrimer A was written by Chen, Yi;Song, Hao. And the article was included in Huaxi Yaoxue Zazhi in 2012.Recommanded Product: 40365-61-5 This article mentions the following:

The precursor compound of anti-tumor natural product ainsliatrimer A was synthesized. The target precursor compound of anti-tumor natural product ainsliatrimer A was obtained by nucleophilic substitution, Wittig reaction, carbonyl radical addition and other key reactions with starting material of tert-Bu (5-iodopentyloxy) dimethylsilane. The target precursor compound of ainsliatrimer A was successfully synthesized, which laid the foundation for the total synthesis of compounds ainsliatrimer A and ainsliatrimer B, through a 7-step reaction with overall yield of 27.1%. In the experiment, the researchers used many compounds, for example, 2-(But-3-yn-1-yloxy)tetrahydro-2H-pyran (cas: 40365-61-5Recommanded Product: 40365-61-5).
