Rearrangement approaches to sesquiterpenes containing multiple contiguous quaternary carbon atoms. Total synthesis of (±)-myltayl-8(12)-ene and (±)-6-epijunicedranol
Srikrishna,Yelamaggad,Praveen Kumar
, p. 2877 - 2881 (2007/10/03)
Details of the first total syntheses of the sesquiterpenes myltayl-8(12)-ene and 6-epijunicedran-8-ol are described. The aldehyde 13, obtained by Claisen rearrangement of cyclogeraniol, was transformed into the dienones 12 and 18. Boron trifluoride-diethy
A biogenetically patterned first total synthesis of (±)-6-epijunicedranol (or junicedran-11-ol)
Srikrishna,Praveen Kumar
, p. 2005 - 2006 (2007/10/03)
The first total synthesis of (±)-6-epijunicedranol (4), employing a biogenetically patterned carbonium ion mediated cyclisation and rearrangement of an enone for the efficient generation of four contiguous quaternary carbon atoms, is described.
First Total Synthesis of (+/-)-Myltayl-4(12)-ene and Single-crystal X-ray Structure of exo-12-Normyltaylan-4-yl 4-Nitrobenzoate

, p. 2259 - 2260 (2007/10/02)
The total synthesis of the unusual sesquiterpene (+/-)-myltayl-4(12)-ene 3 starting from the readily available cyclogeraniol 5 and the single-crystal X-ray structure of the 4-nitrobenzoate 12 of the noralcohol 11 are described.
Stereospecific construction of multiple contiguous quaternary carbons. Total synthesis of (±)-cis, anti, cis-1,8,12,12-tetramethyl-4- oxatricyclo[6.4.0.02,6]dodecan-3-ol, a thapsane isolated from Thapsia villosa var minor
