Selective Monoacetylation of Symmetrical Diols and Selective Monodeacetylation of Symmetrical Diacetates Using HY-Zeolite as Reusable Heterogeneous Catalyst
Srinivas,Mahender,Das, Biswanath
, p. 2419 - 2421 (2003)
HY-Zeolite has been found to be an efficient and reusable catalyst for selective monoacetylation of symmetrical diols and selective monodeacetylation of symmetrical diacetates to form the products in high yields.

The formation of ubiquitous occurring tetrahydrofuran patterns has been extensively investigated in the 1960s as it was one of the first examples of a non-directed remote C?H activation. These approaches suffer from the use of toxic transition metals in overstoichiometric amounts. An attractive metal-free solution for transforming carbon-hydrogen bonds into carbon-oxygen bonds lies in applying economically and ecologically favorable iodine reagents. The presented method involves an intertwined catalytic cycle of a radical chain reaction and an iodine(I/III) redox couple by selectively activating a remote C(sp3)?H bond under visible-light irradiation. The reaction proceeds under mild reaction conditions, is operationally simple and tolerates many functional groups giving fast and easy access to different substituted tetrahydrofurans.
A new approach to the synthesis of royal jelly acid
Zong, Qian-Shou,Wu, Jian-Yi
, p. 399 - 401 (2014/08/18)
A new approach to the synthesis of royal jelly acid (trans-10-hydroxy-2- decenoic acid) was proposed starting from 1,8-octanediol, which included selective monoprotection of 1,8-octanediol with acetic anhydride, oxidation, Wittig-Horner reaction, and hydrolysis and acidification, four steps in total, to yield the product. Overall yield is 80.2%.
