Aldehyde deformylation is one of the useful reactions in biology and organic syntheses this review provides mechanistic insights into same.

New synthetic strategies leading to highly functional erythrina, oxindole and pyrrolidinoindoline skeletons have been developed and an efficient formal syntheses of (+/-)-demethoxyerythratidinone reported.

The first two syntheses of chiral 2,2'-biindoline are reported either in five steps from 2,2'-bioxirane, or three steps from 2,2'-biaziridine, both with exceptional enantiopurity.

The asymmetric total syntheses of hedyosumin E aglycon, 7,10-epoxyhedyosminolide and ent-zedolactone A were realized, with the first two being achieved for the first time.

The syntheses of butane-2,3-diacetal protected tartrate derivatives are described using continuous flow processing techniques with in-line purification and I.R. analytical protocols.

The facile syntheses of a variety functionalized propiolic acids were achieved by carboxylation of alkynylsilanes with carbon dioxide mediated by cesium fluoride under ambient conditions.

Three different protocols for the syntheses of hydroxyalkylnitramines are presented and compared. Safety issues regarding the synthesis of nitramines are also discussed.

Two convenient methodologies have beendescribed for the enantiospecific synthesis of (–)-valeranone 1. The hydrindanone 12, obtained from the readily andabundantly available monoterpene (R)-carvone,has been converted into the ketoaldehyde 16via the alkene 15b. In anotherdirection the lactone 18, obtainedfrom the hydrindanone 12, has beenelaborated into the ketoaldehyde 16employing two methodolo...
