The name of the academician Pavel Vlad is associated with a number of remarkable fundamental and applied ideas. He has determined the priorities for research and some new lines in studies of terpenic compounds, in working out methods of investigation into fine organic synthesis. Under his guidance and with his direct contribution new approaches to determining the absolute configuration of a series of labdanic diterpenoids and of converting them into bi-, tri- and tetra- cyclic compounds have been designed [1]. Novel universal methods for synthesizing tetrahydrofurans from 1,4-glycols [2], olefins from tertiary alcoholic acetates, as well as dienones by means of photodehydrogenation of unsaturated cyclic ketons [3] have been developed by him. It has been established that the Swern reagent not only oxidizes the primary and secondary alcohols in the respective carbonyl compounds, but also dehydrates the tertiary alcohols [4]. The school founded by academician Pavel Vlad is the leader in the investigations of superacydic cyclisation reaction of terpenoids, and also of the regularities of the mentioned reaction in different classes of terpenic compounds, such as alcohols, their acetates, acids, esters, phenylsulphones [5]. Molecular transpositions were performed in the diterpene and sesquiterpene series [6]. Efficient ozonolytic methods for norlabdanic compounds preparation [7], as well as a new theory for evaluating the structure-ambra odor relationship have been also developed [8].
