Next, alcohol 123 is converted to tert-butyldimethylsilyl ether 124, which undergoes dihydroxylation of its alkene moiety with osmium tetroxide (OsO4) followed by oxidative cleavage with sodium periodate NaIO4 to form subunit B [164]. Subunit B is next submitted to a Horner-Wadsworth-Emmons ...
First, draw the minor alkene product that should be formed in the reaction. Second, draw a stepwise mechanism that shows the formation of the major product: Draw the major product obtained when each of the following alkyl halides undergoes an E2 r...

hydroxyalkene; methoxyalkene; dimethyl amino alkene; and dimethyl amino methyldiene. Another embodiment comprises compositions having a formula: also represented as a diene macrocycle, and its pharmaceutically accepted salts, wherein R1 is selected from hydroxyalkene, methoxyalkene, dimethyl amino alkene ...
“A polyene” means a molecule of an organic compound containing more than one alkene. For example, a diene has two C═C; a triene has three C═C; etc. “Target molecule” means the molecule whose changes in concentration in an environment are intended to be detected by a sensor. A ta...
The cyclic peroxide so formed then epoxidises the compound of formula VI by syn specific oxygen transfer to the alkene bond.Preferably, the ketone is of formula (XIX)wherein Ra and Rb are each independently alkyl, aryl, haloalkyl or haloaryl....
Upon irradiation with visible light, this complex undergoes homolytic fragmenta- tion, producing radical A to initiate the reaction. The gener- ated radical A is added to alkene 237, forming radical inter- mediate B. Then, B abstracts a hydrogen from NHC·borane 238 to provide another radical...
