Abstract: Abstract α-Triisopropylsilyl-α-diazoacetone (TIPS-diazoacetone) underwent high-yielding “diazo-side” Mukaiyama aldol-type addition with a range of aryl and alkyl aldehydes when subjected to stoichiometric amount of tetrabutylammonium fluoride at −16 °C, in Et2O. Robustness of the TIPS group makes… read more here.

Abstract: Action of bases on levoglucosenone-derived 6-oxononan-9-olide and 7-oxodecan-10-olide causes the transannular reaction of the aldol type affording stable 2-acylcyclopent-1-en-1-ol and 2-acylcyclohex-1-en-1-ol, respectively. The lower homologue, 5-oxooctan-8-olide derivative, under the similar conditions gives a complex mixture… read more here.
